Software enables user to separate the CAD geometry from CAM toolpath geometry. Original Press Release: SmartCAM v2018 Released Adds New Adaptive Roughing Toolpath Processes New Verification Module for Fabrication and Wire EDM Improved Feed Rate Control Included, much more SmartCAMcnc has announced the release of SmartCAM® v2018. The SmartCAM Computer-Aided Manufacturing (CAM) software family consists of applications for Computer-Numerical Control (CNC) milling, turning, fabrication and wire EDM.

SmartCAM v2018 delivers new Adaptive Rough Milling technology in the Advanced Milling™, SmartCAM FreeForm Machining™ and SmartCAM Advanced Turning™ applications; new Verification modules in SmartCAM Advanced Fabrication™ and SmartCAM Advanced Wire EDM™; improved feed rate control and numerous other useful core additions found in all products. New Adaptive Rough Milling The SmartCAM Adaptive Roughing toolpath results in consistent cutting condition, elimination of full-width slotting cuts and automatically-created adaptive feedrates, which provide end-user benefits of increased tool life, reduced cycle time and reduced shock on their machine.

'Traditional offset toolpaths present several problems such as sharp corners, sudden changes in cutting tool load and shock on the machine tool, all of which can lead to shortened tool and machine life, even breakage,' said Doug Oliver, Senior Product Manager at SmartCAMcnc. 'With the new SmartCAM Adaptive Roughing toolpath processes, the engagement volume of the cutter with stock is constantly monitored and maintained using in-process-stock algorithms. These algorithms handle the changing volume conditions encountered when creating toolpath for the infinite geometric possibilities,' Oliver went on to say.
