Wrapped geometry is flat 2D geometry displayed and machined as if wrapped around a cylinder. You can create geometry in flat or wrapped mode and toggle between flat and wrapped representations. With this option, you can apply all 2D mill processes including contour, pocket, and drill to a cylinder. Because the tool is kept on the centerline of rotation, you cannot control wall angles or tool engagement.
This option also adds the rotary repeat function to milling processes. Output for long, multiple rotations is on a single line of G-code. Post-processed output can support a control’s cylindrical and polar interpolation functions. This option is ideal for parts defined by flat geometry, for rotary part features created by the tool’s shape like simple grooves or pockets that do not need wall control), and for machines without a Y axis.
Polar & Cylindrical Milling
The Polar and Cylindrical Milling option drives one rotary and two linear axes to achieve a 3-axis toolpath. It extends the 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-turn machines the C-axis motion replaces Y-axis motion. You can apply this C-axis motion to the face of a mill-turn part. The input may be flat or wrapped wireframe geometry.
