Fast, efficient bulk material removal is essential to efficient NC programming. Mastercam gives you a variety of techniques to rough machine all of your parts.

• Rough cut multiple surfaces, solid models, STL files, or any combination of the three.
• Rough cut with constant-Z contours or pockets.
• High speed OptiRough removes large amounts of material quickly. The tool takes an aggressive depth cut, followed by a series of quick up-cuts, then repeats the process at the next depth.
• Rough cut by descending parallel or radial cuts, with complete control over plunging with positive and negative-Z motion.
• OptiRest uses Mastercam's in-process stock model to remove stock left from a larger tool.
• Custom plunge roughing lets you rough straight from the top (with no XY motion) in any user-defined cut pattern.
• Constant-Z rough restmill (remachining) identifies and machines areas that need to be roughed with a smaller tool.
• Automatic facing and critical depth recognition ensures flat surfaces that lie between Z-cuts won't be left with too much stock during rough machining.
• Automatically align all your roughing plunge points, making it easier to pre-drill those spots for production machining.
