The GibbsCAM Rotary Milling option drives one rotary and three linear axes to achieve a 4-axis toolpath. It provides a roughing and a finishing mill process for off-centerline Y-axis rotary machining for control of wall angles and tool engagement. Input is 3D wire-frame geometry extracted from solids or created by other means to drive and orient the tool. Optionally, you can use surfaces to orient the tool and limit toolpath.
Tool orientation control includes cutting with the side or bottom of the tool, using a surface or two curves to control tilt, following one curve at a specified lean angle, or using progressive tool lean. Typically, it segments the toolpath, but it can optimize the toolpath helical motion.
