  1. Agreed. It's what made sense to me. Now I'm trying to add a finish pass so to speak. I'd like to leave a certain amount of material for the last pass regardless of the DOC of the previous passes. Any thoughts?
  2. Good day David. Thank you for your support and thoroughness! I was able to get it to work on Saturday. I made some considerable changes. Here's the code, please feel free to critique. Thanks again for all your help! #522=12.249(KEY CUTTER TOOL RADIUS) #523=12.7(ACTUAL PART RADIUS) #524=#523-#522(PROGRAMMED RADIUS FOR KEY CUTTER) #527=15(# OF REPEATS FOR KEY CUTTER) #528=16.36(G50V SHIFT AMOUNT) #529=4.83(KEY CUTTER THICKNESS) #530=16.36(TOTAL MATERIAL REMOVED) #531=#530/#527(DEPTH PER PASS) #544=21.946(PART DIAMETER) #545=[#544+[#522*2]](EDGE OF TOOL ON OD) (KEY CUTTER) (TOOL PROJECTION= 19.60MM-TO NUT) (DIA= 6.28) (*R VALUE ON OFFSET SCREEN=0*) G40G97G98 M5 M80S3=87 T0700 M18C0 G50W-15.

  3. WIll do. Time to make it happen. Thanks again for all the support! Have a great weekend!
  4. It corrected the Y axis value at the bottom of the arc. It's currently Y-30.086 which is correct, but the start position(FIRST PASS) is now coming down on top of the part(to close to centerline).
  5. The results of the test are as follows: The absolute Y value at the bottom of the arc(max engagement) stayed the same regardless of #527 value, which is what I'm looking for. The current issue is the absolute Y axis value at the bottom of the arc=Y-54.584, it should be Y-30.086. It's to far away from centerline. Information I've gathered: 54.584-30.086=24.498 24.498-25.4(#523*2=25.4) = .902(#524*2=.902) Currently #542=55.486(54.584(absolute Y axis value at bottom of arc) + .902 = 55.486) It's really close! I can't seem to see what's incorrect. Thanks again for your time!
  6. Thank you so much! A second set of eyes/second opinion is helpful. I'll test it now.
  7. Yes sir, I saw it. Thank you for the assistance. I posted a question regarding your latest post.
  8. The machine is a Citizen L32. The Y axis is diametrical so if I G0 Y-21.946 (part diameter) it physically moves the tool half that amount (10.973). With that being said, should #540=15.494 or [15.494*2] ?
  9. Attached is the latest edition of the program. It's still not working correctly. When I change #527 the absolute Y value changes. I want the toolpath to finish at the same Y axis location regardless of #527. The only thing I want to change dependent upon #527 is the DOC(depth of cut). 311.TXT (PROGRAM IS IN METRIC) $1 #522=12.249(KEY CUTTER TOOL RADIUS) #523=12.7(ACTUAL PART RADIUS FOR KEY CUTTER) #524=#523-#522(PROGRAMMED RADIUS FOR KEY CUTTER) #527=10(# OF REPEATS FOR KEY CUTTER) #528=8.179(16.358)(G50V SHIFT AMOUNT) #529=4.83(4.699)(KEY CUTTER THICKNESS) #540=[15.494*2]-[#523*2](DISTANCE FROM CENTERLINE OF PART TO BOTTOM OF ARC) #541=[21.946-#540]/#527(DEPTH PER PASS) #542=[[15.494*2]+[#541*#527]](FIRST PASS) #543=#542 (AB TOOLS-KEY CUTTER) (CARBIDE TOOL) (6 FLUTES) (DWG # ) (TOOL PROJECTION= 19.60MM-TO NUT) (DIA= 6.28) (*R VALUE ON OFFSET SCREEN=0*) (#522=KEY CUTTER TOOL RADIUS) (#523=ACTUAL PART RADIUS FOR KEY CUTTER) (#524=PROGRAMMED RADIUS FOR KEY CUTTER) (#527=# OF REPEATS) (#528=G50V SHIFT AMOUNT) (#529=KEY CUTTER THICKNESS) (#540=DISTANCE FROM CENTERLINE OF PART TO BOTTOM OF ARC) (#541=DEPTH PER PASS) (#542=FIRST PASS) (#543=#542) (G10L10P7X0Y0Z15.Q0R0.)(R#522) (G11) /MB7 G40G97G98 M5 M80S3=871(=220SFM @ .9645" DIAMETER) T0700 M18C0 G50W-15.

  10. Would you provide an example. This is relatively new to me. Thank you for your time!
  11. I've attached the blueprint of the part to be made and my code to machine the 5 slots in the OD. My goal is to have a program that regardless of the tool diameter, programmed radius or # of passes/DOC can be changed with relative ease. I'd like to make #527 passes where each pass is #528/#527 deep (the actual DOC is [#528/#527]/2 because the Y axis is diametrical). I've never used variables to this extent so I'm hoping y'all will look it over and critique my code. In the program I accounted for the key cutter tool radius when I programmed the tool path, so the R value on the offset screen=0. I'm cutting on the minus(-) side of Y0. Thanks in advance! 208.txt DWG.pdf

  13. I'm currently not seeing the results I'd like with the G12.1. Attached is the current code (Citizen L20-Mitsubishi control) and the blueprint. The print is in inches but the program is in metric. I programmed the final part dimension + the radius of the tool (.125"), this way the R value on the offset screen is 0. The issues are as follows, the final dimension is approximately .032" to big on the .072" +0./-.004" dimension(width across flats). I've programmed the X and C axis radially. I verified that the tool is centered (X0./Y0.) to the sub-spindle. Also, there's no .127mm(.005") radius on the corners of the square. As the program reflects I'm using G41 and G2's. Per the attached picture captured from the Instruction Manual for the Citizen L20, I should be using G42 and G3's, which is correct? I'm wondering if this is why my part has no .127mm(.005") radius on the corners of the square? Thanks in advance for the support. 300.txt
