1.選擇合理的切削用量 1. Select reasonable cutting dosage 經(jīng)濟有效的加工方式必然是合理的選擇了切削條件，切削速度、進(jìn)給量和切深會(huì )直接引起刀具的損傷，切削速度如果提高，則刀尖溫度就會(huì )上升，會(huì )產(chǎn)生機械、化學(xué)、熱的磨損。一般切削速度提高20%，則刀具壽命會(huì )減少1/2。 Economic and effective processing way is necessarily reasonable selection of the cutting conditions, cutting speed, feed and cutting depth will directly cause the damage of the cutting tool, cutting speed, if increase, the blade temperature will rise, will produce mechanical, chemical, thermal wear. The average cutting speed increased by 20%, cutting tool life by a factor of two. 用戶(hù)要根據被加工的材料、硬度、切削狀態(tài)、材料種類(lèi)、進(jìn)給量以及切深等，來(lái)選擇使用合適的切削速度，有規則的、穩定的磨損是理想條件。 According to users of processed material, hardness, cutting condition, material type, feed and cutting depth etc., to select and use appropriate cutting speed, regular, stable wear is the ideal condition. 2.合理選擇刀具 2. Reasonable selection of knives (1)粗車(chē)時(shí)，要選強度高、耐用度好的刀具，以便滿(mǎn)足粗車(chē)時(shí)的要求。 (1) when heavy vehicles are used, select the tool with high strength and durability to meet the requirements of the rough car. (2)精車(chē)時(shí)，要選精度高、耐用度好的刀具，以保證加工精度的要求。 (2) in fine car, choose the tool with high precision and good durability to ensure the processing precision. (3)為了減少換刀時(shí)間和方便對刀，應盡量采用機夾刀和機夾刀片。 (3) in order to reduce the time and convenience of changing the knife, use machine clamping knife and machine clamp blade as far as possible. 3.合理選擇夾具 3. Reasonable selection of fixtures (1)盡量選用通用夾具來(lái)裝夾工件，不要采用專(zhuān)用夾具。 (1) try to use the generic fixture to install the fixture and not use a special fixture. (2)零件定位基準應重合，從而減少定位誤差。 (2) the positioning datum of the parts should coincide, thus reducing the positioning error. 4.確定加工路線(xiàn) 4. Determine the processing route
