Gibbs and Associates’ Plunge Rough feature is a user-controlled custom process within GibbsCAM 2010 designed to accommodate inserted plunge-milling tools. According to the company, the software enables users to specify machining patterns and multiple variables to control tools and motion for fast plunge roughing with optimal surface finish and tool longevity.
The plunge rough feature is fully integrated and features increased intelligence about stock condition. By tracking where material has been removed, the software can detect safe pull-off direction and distance when it retracts the tool, the company says.
The plunge roughing feature appears as a custom process tile in GibbsCAM’s Advanced 3D machining palette and includes several new options and parameters. Users can specify plunge milling patterns as linear (with cutting direction at any angle), circular, contour or as patterns between two specified guide curves. Users can also select part type as core or cavity; define pull-off motion and distance to eliminate surface marking and minimize tool wear; and specify containment surfaces, containment geometry and stock bodies to control areas to be machined. Plunge roughing contour patters with containment can be performed after specifying faces to be machined, containment faces and the start point of the contour.
