(1) When the workpiece is too high, it should be opened with a knife of different lengths. After the large knife is used to open it, it should be removed with a small knife.
(2) Use a flat -bottomed knife processing plane and use less balls in order to reduce processing time; if there is a slope, and it is an integer, use the oblique knife to process.
(3) Reasonably set the tolerance, so that the processing accuracy and the computer accounting moment are balanced with each other, make more processes, and reduce the time of empty knives.
(4) High hardness of the blank data, selection of reverse milling; low hardness of the blank data, selection of smooth milling. Rough processing reverse milling, refined processing smooth milling.
(5) The knife data is well -durable, and the hardness is habit of rough processing.
