Milling acrylic sfm
WebMilling Guidelines. Milling is a common method for machining plastic parts. In this process, the plastic is held in place while a cylindrical cutter moves on an axis to mill flat surfaces, grooves, shoulders, etc. Both CNC and manual mills are used for plastics. Below are guidelines for milling several performance plastics. WebMore heat is generated in drilling than in most other machining processes. Heat reduction is critical to minimize machined-in stress. A 90° to 118° drill point angle with a 9° to 15° lip angle is usually sufficient for most plastic materials. Acrylic drilling requires a 0° rake angle.
