CNC Router forward speed control

For cutting the CNC Router it into speed adjust to has a very important significance. The size of the feeding rate decides to process the efficiency, but also on the surface quality has the important meaning, and at the same time, the speed change drastically will seriously affect the life of cutter. Therefore, should as far as possible to keep high speed and stable constant surface into to speed (i.e. cutting position relative to the speed of processing surface into). On the other hand, due to the complex curved surface shape, constant surface into the machine to speed will lead to coordinate the constant change of the movement speed, if the cause an movement speed rate changes too high or too big when, will produce larger geometric track error. In addition, due to mechanical moving parts of inertia, in machine tool‘s start and stop and speed changes produce motion impact and influence processing precision, machine tool and the cutting tool life. Therefore, the speed and must according to surface shape and sculpture JiDongLi characteristics of the instructions to speed the necessary adjustments, and need to be changed in speed when using the right speed curve to realize smooth transition. So for the speed processing are generally into to speed pretreatment (forward) and the speed control two parts, the former requirements numerical control system has the function of pretreatment, the latter requiring numerical control system has the function of automatic and deceleration.
