Cimatron 16 increases automation for Mould & Die

Cimatron 16 has been launched by Sandvik, introducing many new features including a new UI and increased automation for faster mould design, electrode creation, and NC programming.

In addition, the latest release adds emphasis on solutions for toolmakers including functionality for die addendum surfaces, mesh manipulation, and drafting detailing.

According to Cimatron, version 16 sees significant CAD enhancements that include the ability to create structural ribs from either a 2D or 3D contour, with draft angle and flat or rounded tops.

Working with mesh models has also been improved with new capabilities for closing open areas, curvature mapping, and the option to define local mesh areas where it is possible to set finer mesh tolerances to describe more intricate model details.

User efficiency continues to be a focus with the process workflow having been improved in several areas including batch printing with support for shaded views, dynamic triad dragging, expanded BOM support for assembly structures, and extended preferences control with the ability to search and reset.

For mould makers, several new mould layout types are now available including a smart mirror and array with the setup wizard controlling the parameters for layout sub-type, rotations, and cavity distances. In addition, a new feature for automated ejector locking has been added that detects which ejectors need to be locked and the type of lock required to prevent their rotation in the ejector plate, and then modifies the head to create the appropriate pocket in the ejector plate.

Surface extension capabilities have been enhanced for both mould and die makers with a new tangent skin extension function which provides the ability to automatically extend surface edges to aid the construction of core and cavity parting faces.

The die design extend faces has also been improved to better manage internal corner conditions that would create overlapping face extensions. In this scenario, Cimatron says it is now possible to replace the affected area with a smooth continuous patch surface.

Conformal cooling can benefit all types of moulded parts and Cimatron 16 now offers more automated methods for superior cooling path generation. Also, a new virtual volume function lets the user limit a cooling circuit to a portion of the shape volume and avoid sections that do not require a cooling channel. Further enhancements include a new optimised curvature function that highlights areas where a cooling channel cannot be created, such as a curve radius smaller than the channel diameter, providing the user with point-and-click controls to correct the channel path.

Electrode design is a critical part of the mold production process and Cimatron 16 adds a number of developments. These include the ability to apply surface-based templates for multi-lump electrodes, EDM setup enhancements for material support with connected manufacturing attributes, and support for System 3R holders.

For the production process, Cimatron says that machining electrodes is easier to control as users can now specify the electrode burning stage from rough through to polishing directly within the NC-Setup. All relevant machining parameters will be applied automatically according to the EDM setup with a new mechanism to automatically create the NC files.

Cimatron 16 sees several CAM developments to support NC automation, with 3-axis rough & volume pocketing now supports the automatic selection of multiple cutters of different lengths for the optimum cutting sequence by splitting the toolpath into multiple operations based on cutting length. This efficiency feature for rough parallel, rough spiral and volume pocket results in better tool selection, reduced tool vibration, extended tool life, and faster cutting speeds.

VoluMill pocketing can now be applied to multiple open and closed pockets of differing heights and depths as a one-step routine and single NC operation. Other 2.5-axis operations include a new capability in the slotting procedure that uses pre-drilled holes for safe material entry and to speed up machining with optimum toolpath movement at each level.

Further efficiency gains should be achievable with new multi-axis drilling routines that consider the real stock model instead of the geometry bounding box. Cimatron says that this creates a starting point closer to the stock for a safer, faster machining cycle.

For 3-axis machining, the geodesic morph and geodesic 3D-step procedures which generate constant surface stepover toolpath for high quality surface finishing are now available for all NC users.

5-axis deburring has been extended to support extra cutter types including end mill, sphere mill, lollipop mill, taper mill and chamfer mill. Importantly, the new multiple cuts feature enables the user to create more than one cut along a sharp edge to generate a chamfer or fillet shape either by constant width or by constant depth for a chamfer, or by constant width or constant radius for a fillet.

Other CAM developments include automatic arc for lead-in/lead-out, additional surface path options for milling, better handling of undercuts for 5-axis roughing, and the ability to import cutters & holders directly from external data formats such as STEP, IGES and STL, as well as Cimatron solid files (ELT). The system automatically identifies the shapes and creates their respective representation in the tooling database table. In addition, the ability to copy and paste geometric data between procedures allows users to efficiently input data between machining procedures, or to multiple procedures, for easy and error-free programming.

Discussing the new release, Cimatron VP Antonio Parisse, said: “We are delighted to launch Cimatron V16 and feel there is a good mix of process optimisation, usability, and new technology that will benefit users in all areas of the product and allow toolmakers to deliver higher quality tools faster, easier and more efficiently.”
