CNC precision parts processing involved in the industry has been more widely, why would say, in fact, in our life, we are all can see, obviously, in some of the mechanical equipment of the above application will be more, if you want to know the CNC precision machining of precision parts processing requirement is high also, why, because the customer in the required quality, And this KIND of CNC precision parts processing itself has great advantages, so it is necessary to do better, more let the customer trust, this is the CNC precision parts processing needs to do.
1, CNC lathe milling plane parts of the feed road
When milling plane parts are summarized, end milling cutter edge is usually used for cutting. In order to reduce the knife marks, ensure the appearance of parts, the cutting and cutting procedures need to be carefully designed.
When the outer appearance of milling is summarized, the cutting and cutting point of the milling cutter should be cut and cut out the appearance of parts along the extension line of the curve, and should not be directly cut into parts along the normal direction, in order to avoid scratches on the appearance of processing, to ensure that parts are summarized lubrication.
When milling the closed inner summary surface, if the inner summary curve allows epitaxial, it should be cut out along the tangent direction. If the generalized curve does not allow epitaxy, the tool can only be cut along the normal cut of the generalized curve, and the cut and cut point is selected at the intersection of two elements of the parts. When the internal elements are tangent without intersection, in order to avoid leaving a notch at the general corner when the knife repair is cancelled, the cutting point of the cutter should be far away from the corner.
The tool path of circular interpolation method for milling complete outer circles is shown. When the end of the whole circle processing, do not at the tangent point 2 back knife, but should let the tool along the tangent direction of the movement of a distance, to avoid canceling the knife filling, CNC lathe tool and workpiece surface collision, constitute the workpiece invalid. When milling the inner arc, we should also follow the criterion of tangential entry, and optimize the processing road from the arc to the arc, so as to improve the processing accuracy and processing quality of the inner hole surface.
