1. Cutter bar positioning: This is similar to the tool positioning of CNC lathe. This needs to compile a positioning program. As shown below, I use Φ 10. The procedure is as follows:
M6 T1
G0 G90 G54 X-5. Y0
G43 H1 Z50
Z0
G1 Z-10 F800
M00
G1 X-10 F1000
Z0
G0 Z100
M01
However, this program cannot be realized on some machine tools, because there is G1 and no speed, the machine tool will think that there is a problem with the program. In this case, G0 can be used for positioning.
2. Fixed positioning: After positioning, find the edge, and then work on the next one, just rely on the positioning directly. Some pliers have a threaded hole on the side, which can also be used for positioning.
3. Line drawing and positioning: When milling a through slot, just draw a line directly on the pliers. Just put it in the approximate position every time you work. The official account of WeChat: UG NC programming. There are also some blank billets, which are larger in size than in the drawings, and can also be positioned in line.
4. Fixture positioning: Generally, the three jaw chuck is used for positioning, and there is no need to find the edge one by one on the clamp. There are also some jobs. The fixtures that need to be done have special pin positioning on them.
