So, I want to ball mill on the face of my part. It's a large radius, these bungs go on the side of a pipe and get welded on.
The plan is mill using x and c, have the machine calculate its own "Y" and Z points, mill across in x, rapid to the same "Y" on the negative side, cut back, rapid back to "Y" positive location and recalc points, etc.
Here's my code-
G00 X20 Z5
G50 S1200
NAT03
M110 (C AXIS JOINT)
G94 M146 M15 M08 (M146 = C AXIS UNCLAMP, G94 = FPM)
G00 X 4. Z-2.63 T030303 SB=604 M13 M153
V1=1.875
N100
V2=3.3125 (RADIUS LEFT ON PART)
V3=[SQRT[[V2*V2]-V1*V1]]
V4=[1.875+.375] (PART RAD + CLEARANCE)
G17
G137 C0 (Y AXIS MODE ON)
G00 X[V4] Y[V1] Z-[V3]
G101 X-[V4] F50.00
G0 Y-[V1]
G101 X[V4]
G0Y[V1]
V1=V1-.03
IF [V1 GE .01] GOTO N100
G136 (Y AXIS MODE OFF)
G95 M12 M09 (MACHINE SPINDLE STOP)
M109 (CANCEL M110 C AXIS JOINT)
G00 X20 Z25 T0100
M02
While it does run, and it does do what I want, the X location doesn't jive with what I have programmed. V4 on the parameter page shows V4 is set at 2.25 which is correct. When the program runs it starts cutting at X5.8576. I have nothing in the tool radius or tip direction for this milling cutter.
I figured i'd comp the radius of the ball mill myself to eliminate potential trouble.
This is the first time I've done a macro program on this machine, and also the first one i've done in probably 10 years.
Anyone have any ideas what's up?
