alright my brain is melting right now and i cannot solve this problem im on.

i want to cut a 360deg circle around a part to a specific dia. in a clockwise direction and the way im coding it my machine just ignors it, it is capable of multi quad cutting. and has done it befor (only that time mastercam wrote the code)

heres what im doing;

the finish radius for the part is R .310 (.620 Dia)
im useing a .500 dia end mill
G92 is in the very center of what i want to be a circle

so techincally from ZERO im putting the tool at G01 X.560 Y0.0 which is the start point of the arc.

now heres where my brain is locking. I is the incre. dis on the X axis from G92 and J is on the Y axis

so for my complete circle AROUND ZERO

it should read (assume G17 G75)

G02 X.560 Y0.0 I.560 J0.0 F3.0

set up like that it should go in a clockwise circle back to the starting point.

or is my I wrong because the actual Incremental distance from my start point to Zero is -.560???

any thoughts???
