For cnc for more surface and more complex parts, the sequence of CNC machining, heat treatment and auxiliary processes should be scientifically arranged and the docking between processes should be solved. Before clamping the raw material, should measure the embryo size is in line with the provisions of the drawings, and carefully check whether its placement is in line with the programming instructions. Self-checking should be carried out in time after the end of rough machining process in precision CNC machining to facilitate timely adjustment of deviation data. Self-checking content mainly contains the location and size of the machined parts.
(1) whether the mechanical parts are loose under processing conditions.
(2) whether the medical parts processing process is the correct starting point for the number of touches.
(3) cnc standard edge (datum point) whether the size of the machined part is in accordance with the drawing.
(4) the location and size of the medical parts. After checking the location and size, the roughing shape ruler needs to be carried out to measure (except arc).
After the rough machining is determined, the finishing of the medical parts should be completed. Medical parts professional precision CNC CNC machining before the shape of the drawing parts, size to carry out self-check: check the length and total width of the positive and vertical processing parts size; measurement of the slope processing parts of the base point size indicated on the drawing.
