How about the milling technology of CNC precision parts processing?

CNC precision parts processing is relatively extensive in the industry. Why do you say that? In fact, we can see it in our lives. The effect is obvious. There will be more applications on some mechanical equipment. You have to know The precision machining requirements of CNC precision parts processing are also high. Why? Because customers are demanding quality, and this CNC precision parts processing itself has great advantages, so we must do better and make customers more trustworthy. This is CNC. Precision parts processing needs to be done.

1. The feed path of CNC lathe milling plane parts
When generalizing outside milling of flat parts, the side edge of an end mill is usually used for cutting. In order to reduce the traces of the knife and ensure the appearance quality of the parts, the cutting-in and cutting-out procedures of the cutting tool are carefully designed.

When generalizing the outer surface of milling, the cutting-in and cutting-out points of the milling cutter should be cut in and out of the part surface along the extension line of the part summary curve, instead of directly cutting into the part along the normal direction to avoid scratches on the processing surface , To ensure that the parts are generally lubricated.

When milling the closed inner summary surface, if the inner summary curve permits the extension, it should cut in and out along the tangent direction. If the inner summary curve does not allow extension, the tool can only cut in and out along the normal direction of the inner summary curve, and select the cut-in and cut-out points at the intersection of the two generalized elements of the part. When there are no intersections between the internal elements, in order to avoid leaving a notch at the general corner when the tool compensation is undone, the cutting-in and cutting-out point of the tool should be far away from the corner.

Shows the path of the tool when milling an outer circle with circular interpolation. When the complete circle machining is finished, do not retract the tool at the tangent point, but let the tool move a certain distance in the tangential direction to avoid the collision of the CNC lathe tool with the surface of the workpiece when the tool compensation is canceled, which constitutes the workpiece to be invalid. When milling internal arcs, we must also follow the guidelines of tangential cutting, and the best organization of the processing path from arcs to arcs can improve the processing accuracy and processing quality of the inner surface of the hole.
