ERROR #1313 - pallet machine caused increased beer consumption to programmer

[Sump Cleaner]

Hi lads and lasses!

I have an idea for programming machines with two pallets and I was wondering if anyone out there could help me out with this.

I am programming 3 Matsuura machines with Fanuc 18i controllers on two and a Yasnac 840Di on tho other one. The machines have two pallets on each with a Chick 4 sided, 2 up per side style tombstone on each.

We are currently resetting G54 to G59 with distances from machine zero to the parts (with G10 in sub programs) every time the pallet is rotated. This works ok but making corrections on the parts is a nightmare, especially if there is an angle hole involved.

The thoughts behind this new idea is this.
- The center of rotation of the pallet is positioned with G54 from machine zero
- The parts are positioned with G52 from the center of the pallet
- Math is applied to the G52 local coord from the offset table for corrections.

This way when you make a change to the X coord on the face of the part (0° position), the machine will automatically change the Z coord when machining the sides of the part (when pallet rotates to 90° or 180°). When you change the Z coord on the face of the part (0° position), the machine will automatically change the X coord when machining the sides of the part (when pallet rotates to 90° or 180°). When you change the Y coord on the face of the part (0° position), the machine will automatically change the Y coord when machining the sides of the part (when pallet rotates to 90° or 180°). This should also work for any angle holes if they are triged out from the pallet center and offsets applied.

Here is sample code for setting the machine and position offsets for the Fanuc 18i.

My questions are...

- Is this feasable? Does anyone have any better ways of manipulating coordinates for programming pallet machines?

- Will it work? Is there a better way of going about programming this? Do I need to use macros or will it work as is?

- Does anyone know how to do this for the Yasnac? Write and read data to variables? The Yasnac has 99 R variables. I can write to them no problem but I have problems reading the into the program.

Thanks to all in advance. If you have any questions please post. I will be watching this thread closely.
