Renishaw probing.

Hi Guys,

I am new here and I was hoping I could get a solution to my problem. I have been a machinist for 18 years and know a lot but I was never hard core in the programming side. I can use Mastercam, but the parts we do are beyond my ability at this time. The programmer has recently jumped ship which left me with running everything and pulling double duty.
I have recently had a project using chick tombstones (machining 3 sides)and I am having a problem with some locations. I have the probe picking up the XY and changing the work coordinate and that has been working fine for O-deg,-90 deg, and 90 deg. My issue is when the tombstone rotates to either 90 or -90 deg my Y locations move around. The bottom of the part is Z-zero and there is a flange that is .075 thick. What I am trying to do is take a Z hit on the top of the flange at O-deg and find the difference from nominal of the .075. Then take that difference and add it to the Y-coordinate at 90 and -90 deg.

This is what I did and it works but it is not giving me the difference of the .075...... Any suggestions.

What machine & where is #137 value assigned? Add notes like I've done here & you may see the issue. You are using P1 as the offset for the probe, & resetting P1 in the cycle. This changes the values of the variable, but I'm not sure if it picks up the new values unless you re-issue the G54.1 P1 code. I'd use a static offset to drive all the probing (say P1), & let it set the values in another (say P2 (S102)), then use the P2 values to set others. That's always seemed easier to keep track of to me.

I'm not sure about this statement I made. Our Monarch's have an optional input for what the result is supposed to be & if omitted, it defaults to 0. But they have their own custom macro's calling these macros. The HMC's do not & just call them as you are. I don't remember if the probed surface would be defined as 0 or 0.075 nor do I remember if there is even an optional input for this on the HMC's. I don't have time to look either as I'm leaving in a couple minutes.

This machine is a Matsuura 5 axis mill.

There are 11 more stations and they have their own individual P#. They go from P1 to P36 and It looks like this'
/G54.1P2X0Y0
/G65P9810Z.3F50.
/G65P9814D.936S102
/#7022=#7022-.001
/#7101=#7021
/#7181=#7021
/G0Z1.
and so on.

I added this in with the hopes of capturing the difference of the .075.

G65P9810Z.3F50.
G65P9811Z.075S101 (probe Z & set P1 Z as the result)
The probe is taking a hit that is supposed to be .075 on the Z...So how would i fix it?

This is the original program. I want to add to it by taking a hit on the Z-0 deg at position z.075 and then if the probe reads it at .076 then take the difference of the .001 and add it or subtract it to the work coordinate when the tombstone rotates to 90 and -90deg...My example at G54.1P1 will change Y position in #7081 and #7161 by .001

I don't know if your doing the variable # math manually, but if so, here's an excel file with the formulas. Just enter offset number & axis number.
