The arrangement principle of the processing sequence of bed parts:

1, the lathe first coarse after fine principle: the processing order of each surface in accordance with the rough leaf semi-finishing _ finishing _ precision processing order, gradually improve the surface processing accuracy and reduce the surface roughness value.

2, lathe datum first principle: the surface used as fine datum should be processed first, because the more accurate the surface of the positioning datum, the smaller the clamping error. Lathe because the 40 outer circle is the coaxiality reference, so the surface should be processed first, and then the other surfaces.

3, the first and second principle of the lathe: the main working surface and assembly base surface of parts should be processed first, so as to find possible defects on the main surface of the blank as soon as possible. Lathe secondary surfaces may be interspersed, after the main surface has been machined to a certain extent, before the final finish.

4, the first near the far principle of the lathe: under normal circumstances, after the workpiece clamping, close to the tool rest of the first processing, far from the tool rest of the part after processing, in order to shorten the tool moving distance, reduce empty travel time, but also conducive to maintain the billet or semi-finished products of the cutting, improve its cutting conditions. Lathe parts of the inner hole, should be processed first inner taper hole, then processing φ30mm inner hole, finally processing φ20mm inner hole.
