Reengineering of a CAM Engine Edited by Chris Felix A s part requirements continue to increase in complexity and the trend for smaller lot sizes forces shops to rethink their approach to adding machine tools, multitasking machines are playing a more signifcant, growing role on the shop foor. Software suppliers are doing their part in meeting the programming demands for this shift as well. At IMTS 2014, Gibbs and Associates (a Cimatron company), developer of GibbsCAM software for program- ming CNC machine tools, is introducing GibbsCAM UKM (Universal Kinematic Machine), the engine behind the upcoming release of GibbsCAM 2015. Tis CAM engine is completely reengineered, taking a new approach to how it will relate to machine defnitions and machine tools. It blurs the line between the defnition of mills and lathes. Bill Gibbs, company CEO and president, says, "CAM systems were designed based on the way mills and lathes were originally created to move. Mill-turns and multi- tasking machines started merging the two. GibbsCAM UKM was created from the ground up with no limitations. It can handle any number of axes in any direction, with multiple tools cutting simultaneously. With this software, users can program and accurately simulate virtually any machine today." A Closer Look Te benefts of the engine extend throughout the entire product line, not just those areas relating to complex machines. Improvements to rendering and machine simula- tion help to give customers the confdence that what they see on the computer screen is what will happen at the machine. Machine simulation and post processors are built on the same kinematic model, optimizing the programmer's time and ensuring complete accuracy. Te new UKM architecture is backward compatible, so current post processors and machine simulation models for GibbsCAM will continue to provide a return on invest- ment. In addition, customers will be able to program and simulate the most complex machines on the market, including machines from Bumotec, Citizen, DMG MORI, Doosan, Matsuura, Mazak, Nakamura-Tome, Okuma, Star, Tornos, Willemin-Macodel, and others. Signifcant changes have been made to the tooling functionality of GibbsCAM 2015. In addition to new tool types being added (barrel, dovetail, convex tip, E-style ISO insert, and tools defned by solids), the software now has dynamic 3D viewing of tools and toolholders in the tool dialog, allowing users to accurately visualize the tools they are selecting for the job. :: GibbsCAM 2015's new UKM engine simplifes the programming of highly complex, multi-axis machines, such as this Swiss-type machine. :: The software is designed for easy geometry creation and toolpath strategies for complex machines such as this B-axis twin-turn, shown with two tools cutting simultaneously.
