Several common positioning methods for CNC machining centers

CNC machining center, analysis of the drawings, programming, on the work, looking for the edge, preparing the tool, tooling, running the program and other steps are essential, indispensable.

In the factory, there are always some batch work is often done, we can program the program saved to the computer, the next time you use it directly out of the transfer into the machine can be. After the above steps, debugging out of the first work and qualified, do not follow this step to come over again, directly on the line on the upper and lower work. At this time you need to do a positioning, then you do not need a seek side, improve the efficiency, but also saves a lot of time.


The following talk about CNC machining centers common several positioning methods.

1. dead positioning.

The following talk about CNC machining centers common several positioning methods.


1. dead positioning.



As shown below, so that after a good positioning, seek a good edge, and then dry the next time, directly by positioning on the good line. Some pliers have a threaded hole in the side, can also be used for positioning.


2. Tool stick positioning.


This is similar to the CNC turning tool positioning. It is necessary to make up a positioning program. As shown in the figure below, I used the Φ10 point drill to position the tool.


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, note that this program cannot be implemented on some machines because with G1, there is no speed, the machine will think that there is a problem with the program, in this case, use G0 to locate it.


3.Special fixture positioning.

General round work with the three-jaw chuck positioning, clip on also do not need a seek edge. There are also some work, need to do special clamps, there are special pins on the positioning.


4. drawing line positioning.


The following figure, milling a through groove, directly in the pliers on a line can be, each time on the live on the approximate location on the line. ug nc programming QQ group: 304214709, there are some blank material, shape than the drawing size, can also be drawn line positioning.
