2019 is a smart manufacturing year, and CNC machining is also moving toward unmanned operation. Will the robot really replace the operator? It can be said that the future trend will definitely be, but first of all, we must solve the problem of machine tool accuracy! Because the machining accuracy of the parts is now controlled by the operator, the CNC skill competitions are held every industry and every level in the industry. In fact, the accuracy of the parts is controlled in a unit time. So how do you control the machining accuracy of parts in CNC machining? I have opened my own processing experience summary process here openly and honestly! I take CNC single-axis parts as an example. I have left a 1mm margin in the tooling before roughing. What is the remaining part after roughing? If the finishing allowance is 0.98mm, and if the tolerance of the part is 0.04mm, it is purely convenient to calculate. I will take the middle value of the tolerance to 0.02, plus the finishing allowance of 0.98 and 1mm. Finally, I cut the two-knife, each radial feed is 0.5mm. If the remaining workpiece is 0.5mm after finishing the first knives, then the second knives do not need to be measured at all. The accuracy must be qualified. of! I explained that it is necessary to divide the turning three times. One roughing removes the remaining material. The two finishing operations ensure the accuracy, because the spindle speed of the first finishing is improved compared with the roughing, and the error of the machine precision is changed. This problem can be solved by two finishing operations. Prerequisites, the second finishing feedrate override must not be adjusted! If you don’t understand the ladder axis if you think about it, you will find that the accuracy error of each axis is different. You must modify the program to make compensation adjustments, right?
