Test Drive Simulation for Subtractive and Additive Manufacturing with CGTech

Subtractive and additive manufacturing are two different strategies for making parts, but both can benefit from simulating and optimizing tool paths in advance. To show how simulation can help avoid equipment collisions and make both subtractive and additive processes more efficient, CGTech is running demonstrations of the latest version of its Vericut software in its booth. Vericut makes it possible to simulate, verify and optimize NC operations ranging from milling to waterjet cutting to robotics. Demos highlight enhancements for comprehensive toolpath optimization, turning and additive manufacturing in version 8.2.

For turning, updates to the Force module help achieve maximum safe material removal. The Force Turning module enables users to optimize lathe turning and mill-turn operations for ideal chip thickness with managed cutting forces and spindle power. The module supports optimal cutting of inside and outside diameters, shoulders, corners and tight spaces, avoiding excessive cutting forces and high spindle power demands.

For additive manufacturing, where material buildup can be problematic, Vericut 8.2 adds realism to deposition simulation. Material deposition can be simulated as-programmed in the additive path, or projected onto the part surface for more natural deposition behavior. With projection, the material build rates vary based on changes in bead overlap, acute corner motions, and starting and stopping at the same location, all of which can cause problems with unpredictable material buildup. Nonconforming additive conditions are identified by warnings, which help users determine when additive strategies are likely to fail, or when it may be beneficial to make a milling cut.

In addition to simulation, Vericut can also be used to determine the most efficient part manufacturing strategy. Product Manager Gene Granata presents on this topic during the IMTS Conference tomorrow at 11:00 a.m. in room W192-C.
