The specific value of the cutting amount
during cnc machining should be determined by simulation method according to the
machine tool performance, relevant manual and practical experience. At the same
time, the spindle rotation speed, the back-feeding amount and the feed speed
can be adapted to each other to form an optimum cutting amount. So how do you
choose the amount of turning in the actual application process? What are the
principles?
(1) When roughing, first consider selecting
a large amount of back-feeding knife ap, secondly selecting a larger feed
amount f, and finally determining a suitable cutting progress v. Increasing the
amount of backing knife ap can reduce the number of passes, and increasing the
feed rate f is beneficial to chip breaking. Therefore, it is advantageous to
select the roughing amount according to the above principles to improve
production efficiency, reduce tool consumption, and reduce Therefore, it is advantageous to select the roughing amount according to the above principles to improve production efficiency cost.

(2) When finishing the car, the cnc machining
accuracy and surface roughness are required to be high, and the machining
allowance is small and uniform. Therefore, the smaller (but not too small)
backing knife amount ap and the feed amount f are selected, and the cutting is
selected. High performance tool material and reasonable geometric parameters to
maximize cutting speed v.
(3) When arranging coarse and fine turning,
pay attention to the range of allowable cutting amount given by the cnc
machining center manual. For the CNC lathe with AC frequency conversion speed
regulation, the torque of the spindle is reduced at low speed, especially the
cutting amount selection at this time.

The above three points are the principle
that cnc processing is the amount of cutting. As a skilled operator, the
cutting amount should be reasonably distributed to ensure the working
efficiency of the cnc machining services china.
