(1) Do not hang the workpiece, flatten and solid the workpiece with the pads of the workpiece. Otherwise, the workpiece declines and upturns during the processing process, and it is easy to knife and workpiece deformation.

(2) Pay attention to the clamping force of the tiger's clamping during processing too much, especially the processing of the plate. Steady force will be tested to deform the workpiece during the processing of processing. According to the characteristics of the precision carving machine, it is less than milling for a small amount of remaining. The cutting force is not very large, so there is no need to use too much force when we clamp the workpiece.

(3) Determine the reasonable loading position of the workpiece, reserve the size of the space, and leave sufficient processing space. Otherwise, interference occurs during processing, and it is easy to damage the knife and tiger clamping.

(4) If it is rough processing, when the amount of workpiece is very large, it is better to use the upper surface of the workpiece before processing, and use the top surface of the milling flat as the benchmark surface of the knife.

(5) Before milling the standard surface, we should find the surface of the workpiece rough. If you find it rough, you can find the upper surface of the workpiece without a watch, and use the pad to flatten the workpiece or put it on the surface on the surface of the tiger clamp to observe the surface observation. Whether the workpiece and block surface are flat.

(6) The pads cannot be greater than the processed workpiece, otherwise the workpiece of the pads that is processed by the pad will not be tightened; Flat and affect processing

(7) In the process of the knife, when the setting point of the Z axis, try to find the height of the workpiece on the surface of the workpiece. Because if the workpiece is a blank body, the parallelism on both sides is not necessarily very high. If we use the workpiece to the knife, the knife of the knife is not uniform when we are milling. Essence

(8) During the meter, the pressure is high to find a positive high point, otherwise it is a low point. The surface of the workpiece is found on the workpiece by knocking on the low point cushion.

(9) If it is semi -precision processing or precision processing, and putting clip processing on the tiger's clamping, we must find the benchmark surface of the workpiece in a formula. Do not clamp the workpiece when you find it. Clamp the workpiece with appropriate strength, that is, the workpiece can also move in the tiger's clamp by knocking. Note: If the parts of the folder are tight, you cannot directly clamp the processing on the surface of the processing. It should be processed by the surface protection or the design of the fixture.
