My first attempt at boring with Mach3.
OD and ID profiles programmed with HSMWorks. HSMWorks cannot handle boring on the far side of the centreline, so I had to post code for the near side of the centreline, then use NotePad to do a global search and replace for all values of "X" with "X-"
Worked a treat.
Material is PVC. End product is an Ultrasonic transducer housing.https://www.youtube.com/watch?v=Zxp-k4pQKTU
