Introduction Machining process Material removal processes with cutting tools Rotating work with stationary,single point tools: turning(车削)，boring(镗孔) Stationary work with rotating,multiple point tools:drilling (钻孔)，milling(铣削)，sawing(锯削) Stationary work with reciprocating,multiple point tools: boraching(铇削) Parameters determining cutting conditions Feed:speed by which new material to be cut is "feed"to a tool Cutting speed:tool cutter (point)speed Cutting depth:depth with which new material is removed Shanghai Jiao Tong University 6
