Hi,
when making mold it is very important to precisely position mold plates on the machine table so that all other plates of the mold base are lined up exactly the same. What you need is WCS in the middle of the plate with zero angle between holes A and B. The best solution would be to use F360 probing to find centre point and angle between holes A/B to be able to use G68. Can this be achieved in F360 somehow?
Solved! Go to Solution.

Hi @iwokowanski,
We can definitely set the datum at hole A with Fusion 360.
We don't yet support programming the angle between 2 holes however if you have Renishaw cycles installed, the cycle you are after is O9834.
You should be able to find how to program this in your inspection manual.

Thank you @Richard.stubley for your reply.
According to the manual here is what I need to do:
1. establish position and diameter of hole A (G65P9814)
2. store data by running "blank" G65P9834
3. establish position and diameter of hole B (again G65P9814)
3. now run G65 P9834 A0 (required angle) D (known distance from hole A to B)
Now I need to add line:
G17 G68 X0 Y0 R#189
to every program I want to run on the given plate. Is that right?
BTW Can I run HAAS VPS cycles to determine necessary data for holes and run G65 P9834 in MDI mode?

Hi @iwokowanski,
Yes this is my understanding that this will work.
You will need to run this for every part, as each part will have a different offset.
I dont think MDI will work as im not 100% G68 persists after the program ends.
You can either add it to your NC code, or if it were me I'd make a sub program and call that.

Please beware! G68 is not the one shot fix we might hope.... There are some rules that I found out have to be followed.
"Turn on cutter compensation after the rotation command. Turn off cutter compensation before you turn off rotation."
That means every time you change tool, you have to activate and cancel G68. I got round this by adding manual nc pass through's.
I hope this helps in some way.

I didn`t know about turning on/off tool compensation. Thanks for the info.
Turning wcs around plate`s hole would be very useful feature for mold makers but this has to be reliable process. I don`t think I can afford to risk a chance that I forget to put manually some line of code to my current operation. I don`t usually run all operations at once. Sometimes I go back and forward with some adjustments of a single operation.
However if there would be probing cycle utilizing G68 on two features that would ease mold manufacturing by far.
