Our job shop does a lot of single run parts, and we use G47 to engrave the manufacturing data whenever necessary. We received a few new jobs that are small piston shapes, and we are using a VF-2TR. Can we use G47 to engrave on the round side of the part? Are there any other canned cycles that can accomplish this? Is there an example program on how to accomplish this?
Sincerely,
Paul
Dear Paul,
Yes, it’s possible to use G47 along with G107 (cylindrical mapping) to engrave on the round side of your part. Below is a sample program that shows the structure needed to make your application possible. Be sure to specify on the G107 line the axis on which you will map the engraving operation.
