Programming Ballpark


This part, named “Ballpark”, will have some drilled holes, a milled circular pocket .2” deep, and some profiling to produce the outside contour. 

Select a piece of   1/4” thick aluminum 601 material from the stock rack.

Ensure that the pieces you select are 5 1/8” x 5 1/8” x 1/4” min. dimensions.

Mill one piece of the material so that you have 2 apposing sides flat and parallel.

Clamp one of the pieces in the vise jaws and using overhand Kant twist clamps, clamp the other unmilled piece on top of the piece held in the vise jaws. 

Edge find the Front left corner of the piece in the vise jaws and set this as the X and Y reference points.

Using a #7 Drill bit drill the holes for the 1/4” bolts through both pieces of material at the dimensions indicated on the print.

Drill a 17/64 clearance hole for the bolts 1/4 deep through the top part (use caution to not drill to deeply into the bottom part during this operation. 

6 - 17/64 Drilled holes equally spaced on a 2.5” Bolt hole circle.

Remove the top part and tap the holes in the bottom piece 1/4” - 20 through 6X

You can push the look button and the display should look like the image below, if not go back and make the appropriate changes.

Now that the Program is entered we need top set the tool so the program knows what we are using for an end mill to cut the profile.

  • Push the Mode key
  • Tool Table
  • Move the highlighted box to the tool #1 position on the upper left by using the arrow keys.
  • Enter .500 for a 1/2 “ end mill 
  • Enter #4 for a finish end mill
  • Push the return Key to go back to mode.

You should now be ready to cut the profile of the part.

Load a 1/2”  (2 Flute) end mill and lower the head of the mill with the quill to within 1” of the top surface of the part by going to DRO-JOG, push the +/-button and then push and hold the Z axis button until the head reaches a position that is roughly 1” from the top surface of the part.

 You should now perform a trial run to ensure that the tool travel will not strike anything as it cuts to part and to ensure that the path is correct.

When everything checks out correctly:

Bring the tool down on top of the part:

  • Set the Z axis to 0 (zero)
  • Press Mode
  • Run 
  • and follow the prompts on the screen
  • Repeat the Run sequence setting the depth .050 progressively deeper than the last step until you have cut through the piece that is bolted down.

You can now move on to cutting the pocket. If you have completed the tutorial “Part with Circular pocket you should follow the sequence described within that tutorial but:

Change the center location of the pocket to X=2.5 Y = 2.5 and the radius to .75

Note: This pocket is cut to a depth of .125 inches

When you have completed the part, de-burr  and show this to an instructor for inspection.
