Document Summary

Objectives: understand basic design constraints from drilling processes, identify basic drilling operations, identify basic types of milling processes, understand depth to diameter ratio related to milling tools, understand basic design constraints from milling processes. Rotating multiple-cutting-edge tool is moved across work to cut a plane or straight surface. Two forms: peripheral milling (left) and face milling. Machining operations can produce many other parts with more complex shapes. Complex shapes need to be produced to very close tolerances and a fine surface finish. (a) slab milling, (b) slotting, (c) side milling, (e) straddle milling, and (e) form milling. (a) conventional face milling, (b) partial face milling, and (c) end milling. (d) profile milling, (e) pocket milling, and (f) surface contouring. Looks like a drill bit but designed for primary cutting with its peripheral teeth. Additional factors relevant to milling operations include: (cid:149) standard milling cutters should be used as much as possible.
