First of all, there's no real point in this, im just trying to figure out how to do it for the fun of it.
I wanna mill a spiral into the face of my part. Say we make a program:
Here the mill will start in X100 Y0, make it's way around, and return to X100 Y0. However, i want it to end it's circle at X50 Y0.Code:[Tool-selection and spindle-speed and all that goes here...] G00 Z100 (Positioning) G00 X100 Y0 (Positioning) G01 Z-3 (Positioning) G03 X0 Y0 I100 (Milling a full circle around X0 Y0 with a radius of 100) G00 Z10 (Positioning)
So the radius of the toolpath gradually decreases as it goes around.
I found this:
(Source: How to make Spiral interpolation G02.1 G03.1 Program - Online Education)Code:First you position yourself at the desired starting coordinates of the toolpath. Next, you add the following line of code: G17 G2.1 or G3.1 X__ Y__ I__ J__ P__ Detail: G17 = Cutting-face X-Y G2.1 or G3.1 = Milling direction X and Y = Arc end point Coordinates I and J = Arc center coordinates P = Number of pitches ( P can be omitted If equal to 0.)
Naturally this does not work with okuma as it does not recoqnize G2.1 and G3.1 (?)
