Drives one rotary and two linear axes to achieve 3-axis toolpath. It extends GibbsCAM’s standard 3-axis milling functions for use on machines with a rotary axis to enable wrapped geometry, cylindrical and polar rotary milling, and rotary repeats. On mills, rotation is typically around the A or B axis, while on mill-turns C-axis motion replaces Y-axis motion. This C-axis motion can also be applied to the face of a mill-turn part. Input may be flat or “wrapped” wireframe geometry.
Wrapped geometry is flat 2D geometry, displayed and machined as if wrapped around a cylinder. Geometry may be created in flat or wrapped mode and toggled between flat and wrapped representations. With this option, all 2D mill processes – contour, pocket, drill, etc. – may be applied to a cylinder. The tool is kept on the centerline of rotation; as a result, there is no control of wall angles or tool engagement.
