| Go back to BobCAD-CAM and open a new NC window. Now go to the drawing screen. We need to put a point inside the center of each drawn circle, you can do this by going to the "point" menu and then selecting "Arc Center" click on every circle you wish to have a point. | |||||||||
|
|||||||||
| Leave the points selected and go to the NC window, select "Machine" and then "Drill and Cycles". The menu displayed on the right will appear. Select "G83 Peck Drill". A window will a appear asking you for the parameters. The "r" value will be where your rapid movements take place, enter 0.1. The "Peck" amount is how far down you drill before coming back up to the surface of the piece to flush chips, enter 0.2. The feed should be about 1.5 IPM. Hit OK and the G-code should be created. Save the file in the same way as the last one. | |

| Now go to Mach2 Mill and move the Z axis up by pressing the "page up" key while holding down "shift", so that you can change the tool to a drill. Now move back down carefully till you are about half an inch off the top of the part then bring the drill down just above the part using the spindle method described before. Now Zero ONLY the Z axis, the tool does not have to be moved back to 0,0 agian(as long as you have not rezeroed the X or Y axis, or moved the hand wheels manually) the tool can essentially be anywhere before the program starts, because the tool will just move from it's current position to the first point in the program. Once all is ready open the program and turn on the spindle and run your program adjusting the feed as you see fit. | |||||||||
