Dispatch of net of machine tool of Chinese numerical control: Line cut production causes an error is to show cut finishs the work that takes and the gap that produce a result to expect to be worth to its formerly. This difference may come from machine tool precision, come from material possibly be out of shape, the likelihood comes from calculative error, come from error of pilot of machine tool computation possibly also. Want to control an error, have to find out a reason, the problem can be solved after settling a matter. Below a few reasons that say to cause an error to arise for us. 1, computational error: This is the person's reason, it is OK checking computations, can prove, also be OK of inchoate discovery. The round with intermediate premature computation, repeat for many times use the irrational number with an insufficient digit (when be like much tooth form) , 10 make into angle make with the second that spend cent promiscuous etc. 2, the machine tool controls a mistake: The frequency that happen second it is few, because the system of machine tool control of nowadays is long-tested, the technology is mature. What make artificially is wrong it can reject to accept, it is accepted the desired result before coming down to also can be being machined or answer 0 examinations. Because rotate for many times,the error of translation place accumulative total answers 0 examinations to also can discover. 3, the precision of the machine tool: This is to point to mechanical precision normally, it is that poor value of real value and theoretical value. The most immediate cause that produces this poor cost is a difference and linearity, verticality. The limits of this poor value should be in 0.
005~0.
02mm less than, this numerical value can be measured, can adjust, with respect to structure of nowadays machine tool, should make this error is worth control to be in 0.
02mm is very easy below, and should arrive 0.
005 it is very difficult below. 4, material is out of shape: Want to have good operation habit only, computation was over to want rehearse, the input was over to want desired result, want before start working school 0, handwheel scale wants to check. Oneself do not have miscalculate, the machine tool also did not go wrong due and enough hold, place remnant was out of shape namely, it is metabolic reason and overcome method should consider carefully only. Work of line cut production produces error no more than with respect to these a few reasons, analyse well, it is OK that according to its generation reason is solved. CNC Milling
