CNC Metal Parts Machining Self-test Process

CNC machining is actually numerical control machining, the first design drawings into the program, and then connect the computer to the CNC machine tools, CNC programming to control the operation of the machine to complete the machining of precision parts. CNC machining is mainly applied to small batch, a variety of types of workpiece machining, and CNC machining precision is very high, so much for precision parts machining.


1, CNC lathe processors must know the contents of the process card before machining, know the parts, shapes, sizes and parts of the drawings to be machined clearly.


2, the workpiece should be measured before the blank size is consistent with the drawing requirements, the workpiece clamping must carefully check whether the placement and programming instructions consistent.


3, after the completion of roughing should promptly self-test, in order to make timely adjustments to the error data. Self-test content mainly for the location of the machining site size.

(1) whether the workpiece is loose;

(2) whether the workpiece is correctly classified;

(3) CNC metal parts machining parts to the reference edge (reference point) the size of the drawings meet the requirements;

(4) CNC machining position between the size of each location. After checking the location of the size of the rough shape of the ruler to be measured (excluding arcs).


4, after roughing self-test before finishing. After finishing the workers should deal with the shape and size of machining parts into the self-test: the machining of the vertical surface of the detection of the basic length and breadth size; machining of bevel on the drawings measured on the base point size.


5, the workers to complete the workpiece self-test, confirm the drawings and process requirements before the workpiece can be removed to send inspectors for special inspection.
