Principles of processing operations:

Tool concentration

That is, according to the process of dividing the tool used, the same tool can be used to machine all the parts that can be completed on the part _, and then the second and third knives can be used to complete other parts that can be completed. This sorting method can reduce the number of tool changes, compress the dead time, and reduce unnecessary positioning errors.

Benchmark current principle

Machining positioning datum

First coarse

  After the benchmark plus _ work well, according to the shape, dimensional accuracy and other factors of the part, the processing of the whole part should be the roughing process before, followed by semi-finishing, finishing, finishing, to gradually increase the surface of the addition _ Precision and reduced surface roughness.

Live first time

The main surface and the processing of the base surface are arranged first, so that defects which may occur on the main surface of the blank can be found early.

The secondary surface can be interspersed, placed on the main surface to a certain extent, and before final finishing.

Divided by processing location

First face and back hole, first outside and inside, first simple and then complex, first precision and high precision.
