Parts size is small when machining parts, how to adjust?

In the process of machining, the tool abrasion will be caused by the long cutting time, which will directly cause the product size to be too large or too small. If this happens during the machining process, it will prompt us to add tool wear compensation. There is a tool Length abrasion compensation and tool radius abrasion compensation, these two compensations are very important to machining center operators and programmers, so how to use them?

Tool length compensation is used for length compensation due to tool wear during machining. Generally, negative tool compensation is added. Find H behind tool 8 in the compensation page, add compensation value below H, and add positive tool compensation tool upwards Take the No. 8 tool in the tool magazine as an example. G43H08Z80.

Tool radius compensation is also compensated for tool wear afterwards. It compensates for the tool radius. For example, a tool with a tool diameter of 16, after three pieces of steel are made, the tool diameter becomes 15.96, then it is necessary to add tool compensation. Clockwise add negative tool compensation, the format is that tool compensation -0.04 is written in the tool radius compensation D behind the 8th tool. If the size is small in the machining process, positive tool compensation will be added. G41D08X4.56Y5.87F1500.

After the tool compensation is added, check whether it is correct or not in time. In addition, if you change a new tool, remember to clear the tool compensation in the original tool compensation compensator, otherwise it will read the tool compensation inside, which will affect the quality of the processed product.
