You will get better answers if you come across someone who can program.
Here is a simple sample I wrote for you.
This program starts at B0 Y0 Z2.5 (5" diameter part) and does a 1" radius at 90 degrees and the continues along it's merry way to B360. Yes, this is a proven program.
Ready? Here goes:
O0005(C AXIS TEST)
G0G90G54X0Y5.B0M3S600 (Start at B0 Y0.)
G43 H36 Z10.
G1 Z2.5 F50. (5" diameter)
G91G17Y0B0 (specifies your programmed arc plane. B substituted for X in G17)
(notice G91 to prevent actual movement)
G107B2.5 (turn on G107/7.1 and calculate profile on 2.5 radius part***important***)
G90G1B67.0821F30.(start of 1" radius at 90 degrees)
G2Y5.B112.9187R1.(end of 1" radius at 90 degrees)
G107B0. (Turn off G107/7.1)
in order for this to work set parameter 1022 as follows:
this sets the substituted axis as X for calculating radii in G17 plane.
