What Is Milling Technology Of CNC Machining Parts ?

For precision CNC machined parts processing is still widely involved in the industry. because we can see it in life, it has a significant effect, and it will be more applied to some mechanical equipment. we must know the requirements for precision machining of CNC precision parts are also high. Because customers demand quality, and the advantages of this kind of precision CNC parts processing are great, they must be better and more trusted by customers. It is the precision CNC machined parts processing. need to do well.
Feeding path of CNC milling plane parts by CNC latheWhen generalizing milling plane parts, the side cutter of an end mill is usually used for cutting. In order to reduce the connection marks and ensure the appearance quality of the parts, the cutting-in and cutting-out procedures of the tools are carefully designed. When generalizing the appearance of the milling, the cut-in and cut-out points of the milling cutter should be cut into and out of the part along the extension line of the part's general curve, and should not be cut directly into the part in the normal direction to avoid scratches on the appearance and ensure the part. Summarize lubrication. When milling the closed inner outline appearance, if the inner outline curve allows extension, it should be cut in and out along the tangent direction. If the internal generalized curve does not agree with the extension, the tool can only cut in and out along the normal direction of the internal generalized curve, and select the point where it is cut in and out at the intersection of the two generalized elements of the part. When the internal tangent elements are tangent and have no intersection point, in order to avoid leaving the notch at the generalized corner when the cutter compensation is withdrawn, the cutting point of the cutter should be kept away from the corner.
When the round machining is completed, do not retract the tool at the tangent point. Instead, move the tool along the tangential direction for a certain distance to avoid the cancellation of the tool compensation. 
The CNC lathe tool will collide with the appearance of the workpiece and constitute the workpiece as invalid. When milling internal arcs, you must also follow the tangential cut-in rule. The optimal organization of the transition from arc to arc is to improve the cnc machining accuracy and quality of the outer surface of the inner hole.
