Milling, turning, and routing

Milling also refers to the operation of producing a groove or slot in the flat surface of sheet stock, a product or a die, as well as to finish surfaces. See milling, turning, and routing. 

Adequate support and suitable feed rates are very important. For many plastics a surface speed of 500 Itynun with feeds (depth of cut) of 0.002-0.005 in. per revolution will produce good results. The feeds and speeds should be similar to machining of brass or aluminum. Appendix I gives milling, turning, and routing data for various plastic materials.
