New dimensions for milling

Mastercam 2019 Mill, available in the UK from exclusive agent 4D Engineering, offers expanded machining flexibility and an increased emphasis on speed and automation.

2D high-speed toolpaths, 3D enhancements, and multi-axis features combine with dozens of additional new enhancements in the software package intended to improve shopfloor productivity.

Some of the 2D enhancements include a new toolpath, Model Chamfer which allows users to machine safe horizontal chamfers on solid models. After selecting a geometry, Model Chamfer has several parameters to further control the toolpath.

Another new 2D feature means users can maintain sharp corners for standard 2D contour and pocket toolpaths. This new option allows the user to roll the toolpath around sharp corners and is available when a positive value for stock is entered to leave on walls.

New 3D features of Mastercam 2019 Mill include an added 3D high-speed toolpath. Equal Scallop, creates a consistent scallop motion relative to stepover distance, and produces an excellent surface finish. The feature generates clean, noise-free motion with the ability to smooth out sharp corners or convert the motion to a spiral approach while avoiding stepover moves.

Additionally, the linking process time for Area Roughing 3D toolpaths has been improved, specifically for parts with many pockets and small step downs. This improves the overall processing time for high-speed machining applications that use high feed endmills.

Another enhancement means projected boundary smoothing tolerance has been added for Hybrid and Equal Scallop toolpaths. When the user projects a containment boundary onto the machining model, the resulting projected boundary can be jagged or noisy, especially near steep features. Using this option allows Mastercam to improve the quality of the projected boundary.

The multi-axis improvements in Mastercam Mill include a new toolpath, Deburr, which can be used to break edges for 3- to 5-axis operations. Deburr can be used with a ball end mill and a lollipop with undercut tools.

Morph and Parallel toolpaths now support a gradual Front shift which keeps the tool in better contact with the part, without placing excess wear on the tool’s leading and trailing edges. Without it, the tool cuts across the part with the tool’s edge.

Also, Curve, Swarf, Flow, Multisurface, Port, and Rotary toolpaths are now multithreaded in Mastercam 2019 Mill which allows the software to operate while the toolpaths are generated and allows for speed improvements in multiple and offset cut calculations.

Other powerful tools in Mastercam 2019 Mill include: Check Holder enhancements, accelerated finishing, Skip Pocket Smaller Than, a new parameter that enables programmers to skip pockets based on the tool diameter percent, rather than by entering a dedicated size of the pocket and new Point Selection Workflow and Transitions Feed Rate options which allow the user to set which feed rate is used during transition moves for Waterline toolpaths.
