2010

(16) A new algorithm for the "rest milling" has been introduced. Up to now it works only when some surfaces are selected and when the optimizations of XY steps are disabled. This new algorithm generates a smoother toolpath, while calculation times are greatly reduced.

(15) It has been added a new machinings management for disc tool roughing dedicated to marble sector.

For this kind of work, it has been created a new window of parameters configuration.

This window will be active by input the option <QD> in the machining name. For example: roughing <QD> The window is shown in sequence after the standard ones, normally used in these machinings. With these parameters is possible to manage disc roughing by cycle, by zone, by faces or quadrants, just managing the machinings of the rest material and optimizing approaches and retractions.

(14) New update in the "AMM" module (ver. 0910).

In this version it has been improved the machining of "Curves" and "Swarf machining".

Now the library includes the multicore version too, which allows to speed up all the calculations.

The news in this release are:

a) introduced a new kind of link: "Step". It is very useful especially when machining mesh surfaces.

b) the speed and quality of the Swarf machining have been improved.

c) In the stock management it has been introduced the definition of stock with undercuts.

d) In the kinematics simulation it has been added the calculation of machining time, the visualization of the coordinates of the collision points and the grouping by cycles in the collisions' report.

(13) A new command has been introduced in the Collision check of tool components.

In addition to the choices: "Collision toolpath deletion" and "Z shifting of collision toolpath", you can now find the new option "Tool axis tilting where needed". This choice can be applied when using "spherical" tools to obtain the automatic tilt of fourth and fifth axes to move the tool's shaft away from the object, maintaining the contact between the tool and the working surface. This option doesn't require any further parameter and can be applied to any machining. This important innovation allows the 5 axes continuous machining also on external parts of the model, for instance by "Contouring" or "3D profile pocketing" and also while performing roughing or undercut machinings.

With the addition of this powerful automatism, this product becomes a unique system with top-level performance and effectiveness, either on 4 or 5 axes machines. The high speed 5 axes machines will finally express their dynamic performances at the best, becoming the indispensable and ideal partner, having their strength in the velocity and precision of 5 axes continuous machining.

(12) New update of the "AMM" module (ver. 0610).

In this release have been added two new kind of machining. Start the strategies' window, in the field "Calculation based on" you will find the possibility to choose the surfaces and beside that, the following machinings:

a) Wireframe, tipically a 5 axes finishing machining, which uses additional lines for the tool orientation to set the desired slope in each area.

b) Swarf machining, in this case the side of the tool is placed between two drive curves. In this case it is possible to set or not some drive surfaces to calculate the tool's orientation. The calculation of the passes between the two drive curves can be performed with different optimization' s options. This machining includes the roughing management too.

(11) Now available the new release to import the following CAD files: Catia V4, Catia V5, NX (Unigraphics), PRO/E, Inventor, Solid Works and Step. It has been improved the management of the new 64bits platform of these CAD and the assemblys new management.

We reccomend you to download it as soon as possible.

(40) In SUM3Dental we can mill an Implant Bridge without cylindrical hole inside the Model. In machining name add the "BREAK" word and the software calculate the drilling also without cylinder.

(39) In SUM3Dental there is a new icon to manage the shrinkage factor. there are 2 applications for this icon: the first when you don't remember the scale factor used during the importation of the model; the second when you need to mill in Zirconium the same file done in Plastic or Wax. In this case it is not necessary to reimport the model.

(38) In SUM3D dental a new command has been added. Is now possible to select only support pins we want completely cut.

Durind the STL import step this new feature automatically creates GREEN and RED support pins:

GREEN pins are connectors will be completely cut (by following the tooth surface, if strategy expects it),

RED pins are connectors will not completely cut in order to hold the item to the stock (then to avoid the detachment between item and stock).

These two different machining strategies must be added or just existing into strategies.

The "Select the cuttable holders" command lets to manually define connectors to completely cut (green) and connectors to don't completely cut (red).

(37) Add a new parameter in tools archive. It's the xy feedrate when the tools is in the full material. This parameter it's used only in the Pocketing.

(36) SUM3D Dental: in the optional importer now it's possible import the Etkon (SCN - NMDL) format.

(35) SUM3D Dental: it's add the possibility to avoid to change parameters with a flag in default parameter, strategies.

(34) SUM3D Dental: in the optional importer now it's possible import the Sweden&Martina (COF - XTL) format.

(33) SUM3D Dental: now it's possible mange the shrink value for the sintering process like a % or like a fixed value. Go to default setting, Model import.

(32) SUM3D Dental: It's possible manage the shift of the raw during the importation. If the flag it's active, during the import process will ask the shift value. Normally it's used when the equipment can manage more than one disc.

(31) SUM3D Dental: Now it's possible to add a picture to personalize the desktop. In default setting, Configuration you will find all information.

(30) The archives of the optional importers are updated (Catia V4, Catia V5, Pro/E, NX (Unigraphics), Inventor, Solid Works and Step).

This update is necessary for the compatibility with last 2009/2010 versions of mentioned CAD systems.

(29) In SUM3D Dental a new parameter has been added; in "Default settings -> Model Import" window in now possible to "Keep the original position" (Yes/No). That parameter lets to deactivate the "automatic translation of imported models" that avoids overlap with previously imported models.

(28) In SUM3D Dental the "STL import" window has been modified. The "Surface Reposition" flag has been removed (system automatically will do that).

(27) In SUM3D Dental a new command has been added, is now possible import the equipment.

(26) In SUM3D Dental "5 Axis Full" version a new strategy to machine the undercuts parts with 5 axes in continuum has been added.

(24) In SUM3D Dental "Accurate Positioning" command has been modified. Now it lets also to roto-translate links.

(23) In SUM3D Dental "Create link" command has been modified. Now it's no more necessary use lenght, the link will be create depending on existing offset curves.

(22) In SUM3D Dental now "Create link" command can also connects two elements. In this case the link's length will be referred to effective distance between two elements.

Other dimensional parameters remain same as standard links.

(21) Added new "Sum3d Dental Statistics" command in Utility menu. That runs the statistics manager optional module.

(20) Added new "Show Oppisite Side" command in Display menu for a "different color" display of surfaces to be machined. It's really useful to better show parts of the model to machine in 4/5 axes; the opposite side of machining side (also showed with a vector) will be showed with a different color user selects after command start.

(19) in SUM3D Dental, a problem in "Accurate positioning" command has been fixed; now is possible rotate the object on XY plane and "+/- 180" degres only, just in case the "Bounding Box Optimizer" is enabled (in STL import procedure) and you have a 4 axis machine (Default settings\Strategy\Number of axes = 4).

(18) A problem in "Create Cross Section" command (Curve menu) has been fixed.

(44) In the two curves machining it has been added a parameter for the management of Intermediate retraction positioning. In case of machining on large sized models, and with great variation in Z, it is possible to manage intermediate positioning: minimum possible Z, maximum Z or highest point of processing.

(43) In the calculation of machining times it has been added Rapid paths. This means that the calculated times will take into consideration all the parameters, including the input of machine data (machine archive), accelerations/decelerations and effective speed of rapid paths.

(42) In the machining of 5 axis curves is now active the parameter Path sharp corners rounding. This allows the introduction of small radii on all corners present in the path. In this way movements due to the change of path direction are smoother.

(41) New commands to memorize the history of the model. This set of 3 commands in the "Configuration" menu allows to display the operations of rotation, traslation, mirroring and scaling performed on the model starting from the acquisition.

Enabling the command "Model History", and than " Show model history" its possible to verify operations and values applied till then. The command "Delete model history" resets the status. This choice consents to check the performed operations avoiding mistakes or wrong repetitions.

(40) Added the management of the postprocessor for CNC TPA for a direct programming in the specific format for the machining of wood.

(32) New parameter added in the machining of 3D profile pocketing. It is the parameter "Dont mill the external borders of the surfaces", displayed with an additional window when choosing fields "Selected curves " and " Machining area defined by selected surfaces". In this way its possible to set up if you want to machine or not surfaces external edges, in practice if the tool must rotate around corners. To ease this function the external vertical surfaces have to be de-selected.

(31) In wire erosion theres a new parameter to consider NURBS surfaces while calculating the cut with the related syncs required from this kind of surfaces.

2006

(7) Now it is possible to define and use the raw part on every existing machining strategies.

(6) After having calculated any kind of machining, it is possible to trim it in relation to any previous machining of which the rest material are calculated. In this way a rest milling is obtained.

(5) In the pocketing machining, the possibility to pocket with unidirectional parallel passes or with Zig-Zag with angle has been added; this possibility is added to the consolidated removal method with concentric passes with removal techniques for high speed machining.

(4) The SUM3D machining tree, existing from version 7.0, is enrich of a new level. This feature allows the machining rationalization, keeping them under logical structures.

For example, defining a group Roughing, it will be possible to include all the single machining that finalize the roughing cycle of the workpiece. This new level is also used by the Drilling Wizard, already seen in the previous paragraphs, in order to obtain under a single item drilling, all the necessary cycles for their machining (i.e.: centering, drilling, boring, flaring, etc.).

(3) Thanks to the acquired experience with the AMM module, SUM3D is enriched of additional module (Option) for the machine tool kinematic simulation. As the one included in the AMM module, the kinematic simulator allows the workpiece visualization during its machining.

In this way it is possible to show all machine movements in action on all the axes, linear or rotating. The standard machine tool library, already provides several type. Anyway this library can be customized with your machine.

(2) Drilling configuration. A new area of development is related to the management of the machining performed along the tool axis, like simple drilling, threading, flaring, boring, etc. or complex like deep drilling with boring an flaring or chamfering or threading.

The group creation, customizable, is made through data input in a Wizard dialog and allow to perform a complex machining (with multiple tools) in a single command that includes all related parameters. The machining tree changes its aspect where you can see the drilling sub-machining. The group with this sub-machining allows, for example, to work on four face of a workpiece, automatically repeating the same operation for every face, specifying the rotation of the mandrel axis, the limits of working area and the data to generate the part program.

Moreover, through a customizable window, you can define the drilling rules for any kind of complex drill, following the method and the order used in the shop floor.

These data can be stored as MACRO in order to reuse them on every round geometry that identifies the machining position or, for a 3D drawing, on every cylinder portion that identifies the position and the automatic head or table orientation.

(1) Tools table related to the materials to be machine. In SUM3D ver. 2005 a new material table has been introduced. It allows the list of materials with the cutting technological parameters to every tool archived. The parameter definition is very simple and intuitive, thanks to the dialog windows. It is possible to make it during the tools library creation process or at any following time. This tools list can be exported to other SUM3D licenses.

2005

(17) In the contouring parameter table, the parameter machine form bottom to top has been added.

(16) Pocketing/contouring parameters change,. The contouring type parameter in the contouring machining, that provided the choice concord/discord/bidirectional has been moved in the parameter table, common to the pocketing and contouring machining. It has been modified in Machining type, with the same option. This change allows to execute the pocketing on discordance or bidirectional way.

(15) The components related to the optional importers (Catia V4, Catia V5, Step, Pro/E, Inventor, UG) has been updated. To do that it is necessary to install the related updater (100 MB) available on the web site. The update offer an important improvement in the importing time.

(14) The possibility to load a shaped tool has been added to the tool library. With this function it is possible to draw the tool with a CAD system, loading it in the archive and using it in the curve machining (marble, wood, etc.).

(13) The new pocketing algorithm, provides to machine in concordance, discordance or bidirectional. In case there are not concordant movements with the choice made, SUM3D will execute a reposition to grant to work always in the selected more.

In case of pocketing, several automatism are available. They provide the calculation from external to internal or vice versa depending how the surfaces to be machined are shaped. For example, if a mould is machined, the calculation will be executed from outside to inside. Working on a cavity, the calculation will be done from inside to outside. In case of a cavity with open wall, the software will check the total development of closed and opened areas and, if the open areas predominate, the develop of the toolpath will be from inside to outside or vice versa.

The new algorithm provide the raw part management, that is possible to define the raw part (to be activate on layer) with imported or created by SUM surfaces, so that the working passes are related only to that areas.

The optimization of the removal section activate specific behavior, useful in case of hard material machining or in the high speed machining. In this case, every time the tool is located in an area where it is necessary to remove material from stock, a trochoidal movement will be generated in order to create the wide area to allow the following correct machining. The descent in a narrow areas will be machined with helical passes. According to the shape of the area under machining, the excavation passes will be generated with offset movements or with passes along a direction. The starting point where the tool descent, cant be outside from delimiter profiles or from XYZ limits. The application of the maximum descent angle (or vertical descent) in the material is bounded by the downloaded in the lower part tool configuration. Indeed, setting NO in this parameter, the tool is avoided to descent into material in a vertical direction or with an high descent angle.

In the contouring, the new algorithm provide:

a) set the machining sequence by zone or by Z

b) machining from top to bottom or vice versa

c) delete the border toolpath, that is in case some model surfaces are selected, the tool can avoid to bypass the edges.

Always in the contouring, the new algorithm provide, even is not set, a detachment from the surfaces before the reposition for a new pass.

(12) In the SUM3D simulator, several new command for the raw part definition has been added.

Area definition, this command allows, through some windows, the activation of the raw type to be represented and its related values.

If any raw part is defined, one will be generated with the maximum XYZ encumbrance of the simulated toolpath. The choices of type of raw part are:

> Parallelepiped, the minimum and maximum XYZ are requested. It must be active or not.

> Cylinder, the lower and upper radiuses together their center coordinates are requested

> Sphere, the radius and the center coordinates are requested, together the option to create an hemisphere.

> Mesh, tell the use of the raw part included in a SUM3D layer and activated as raw part.

> Curve, tell the use of a curve included in a SUM3D layer and its activation as raw part. In this case it is necessary to set the raw part height.

(11) In the tool archive the possibility to add a tool list from a CSV file (achievable with Excel or a test editor like Windows Notepad) has been added. To activate this functionality, you have to choose the CSV type during the import phase. With this selection, it is possible to import any text file that uses a separator (; as default). This file have to be made with an header where the name of fields included in the SUM tools archive are defined (file tools.arl placed in the SUM folder). In the below lines, the related parameters have to be included as the following example:

Machine;ToolType;ToolNumber;Diameter;Length;Description;

ZTestAxis;1;1;10.5;50;description test CSV;

ZTestAxis;2;10;100;150; CSV;

;14;;111;111;;

(10) There are many news added in the last three months, here below you can see the details:

a) perform rest milling with every machining strategy with raw part update.

b) automatically work as pocketing/contouring with continuous spiral toolpath in cavity with vertical wall.

c) use disc tool (cylindrical/toric/spherical) on undercut machining with complete collision check of tool and tool holder.

d) use the strategy of 3D curves pocketing in the rest milling with constant machining allowance. Moreover, in case of Zig/Zag rest milling, the inversion of machining direction has been done outside the workpiece (High speed).

e) managing, through the max tool length command, the same machining with different tool length. In this way it is possible to machine deep cavities or complex surfaces with the same tool that works with different protrusion, giving the possibility to work faster when the tool has less overhang and reduce it where a deep machining is needed.

f) managing, through the command Tool component check, the behavior of the collision check. This parameter, besides the enabling of this control on tool and its components (Mandrel, etc.), allows to define the behavior between the possibility to delete or raise the collision toolpath in order to use the Update rest function, also on the indexed 5 axis machining.

(9) To avoid creating conflicting behavior using traditional tools (toric or spherical) on undercut machining, the possibility to use not shaped tools has been disabled. To perform undercut contouring machining is now needful to use a shaped tool.

(8) In the SUM3D accessories, the new command mesh reduction has been added. It allows to reduce, by percentage, the visualization and/or machining meshes.

(7) In SUM3D it is now possible to update the rest material map (apply toolpath in show rest material) even in case of machining executed with non vertical tool axis. The display remains as grid, therefore is not possible to show the undercut.

(6) In the XY contouring machining, it is possible to select constant scallop height rest milling as a new mode: Concentric 3D passes in low slope area. It allows to automatically machine as 3D pocketing mode, the areas of the model with a slope less than 45 degrees.

(5) In the curve machining, the possibility to select circular profiles that intersect other profiles has been added. In this case the areas intersected by those profiles are excluded. This function is particularly useful when shapes have to be cut with milling, leaving some areas not machined that allows the cut object to avoid to follow down, avoiding also a possible tool damage.

(4) The below two commands has been added to the curve menu:

a) The curve orientation command, allows homogenize the curve direction, in order to avoid to try several time the curve selection in curve machining.

b) The central profile computing command can be useful, for example, in two situation:

- in engraving to determine the central curve of a writing in order to follow it with the center of the tool and avoiding that the font width will double the tool size when the outline of writing is machined.

- in the machining (eg: flattening) where is needed to follow a center path with a tool in order to obtain the removal with a single pass of the material between the selected curves.

(3) In the curve machining the new parameter Curve to determine the machining sequence has been added. It allows to set a curve where its path is used to identify the machining sequence of the selected curves (it is not applied in pocketing). The curve intersection sequence set by the profiles that will be machined, will correspond to the sequence of their machining.

(2) In the curve machining, now it is possible to set the starting point, placing small rectangles on the curves, similarly to the existing possibility to place small circles to create microjunctions.

(1) A new item in the tool parameters has been added: feed without material removal that lets to set the feedrate to be applied to the working movements (G1), where the tool do not remove material.

By now, this kind of movements has been identified only on pocketing and contouring machining, but will be extended to more of them. The working movements where the tool do not remove material are, for example, the connection movements during pocketing, that are made at working speed because the tool is moving close to the material even if there is no material removal.

With a correct use of this parameter, it could be possible to save time on these types of machining.

This kind of movements has been shown with a pink-violet color, close to the red used for standard toolpath.
