I just started trying to learn CNC with my Hardinge CHNC and Fagor 8025GT.
I'm drilling and boring a 7/8" piece of steel round stock and need a hole .563" wide and 2.237" deep.
I've had good luck with using G83 canned cycle to drill a hole to accommodate my boring bar. I now have a .498 hole the depth I need. I used dead center location as offset numbers for the drill. I don't know how exactly I did it, but it worked.
Now I'm having trouble trying to figure out how to finish the hole to .563 with a boring bar.
I followed the instructions for tool offset in Jog mode with the 7/8" stock chucked. Named my tool #3 T3.3, and jogged the tool in X touching the ID of my hole. Instructions said to enter the stock diameter "F7" (T.meas), but I entered the wall thickness left on the stock... "X.137" "enter" "X" "F2" (load).
Then Jogged in Z to the face Z.010 "enter" Z F2, then F7 to exit.
Next I tried to use G68 turning cycle. It does a nice little dance, but I'm way off. Here's my code:
NO (BORING 7/8" STOCK.563 WIDE 2.237 DEEP)
N10 G90 G95 S750 T3.3 M4 M8
N20 G00 X1.098 Z1.320
N30 G1 F.004
N40 G68 PO=K .1098 P1=K.125 P5=K.010 P7=K.097 P8=K2.237 P9=K P13=K1.099 P14=K.1100
N50 GO Z5.5 M9 M5
I don't even know if I'm using the correct canned cycle. All I want to do is remove material 2.237 deep in the hole to open the ID up to .563.
Any tips would much be appreciated.
Got it handled.
