Micura 500-500-500: Force all probe movement to +Z and +Y.

[[Ri...]]

I have always struggled with restricting clearance planes. On our two Micuras, we have minimal space for Probe and styli changes. Every part axis lays in the X axis; all probes change in the +Y axis (To and from the rack).

I want to add more clutter to the CMM, most likely a Stylus cleaner, from this I want to force all stylus changes that use -X and +X to always go over the top of the fixturing/Parts.

All of my Styli are either -Z or -X and +X.

I do not want any probe travel in the -Y axis based on the Base Alignment.

Any help is appreciated.

There is just enough room at the Probe rack for the Sensor to pickup/Drop off probes.

Very interested in an answer to this We have some fixtures that are almost tall enough to interfere with a Y move going to the MSR. It already uses the height of the lowest rack position when returning.  I seem to remember a long long time ago , a calibration tech changed an old contura to a Z max position. but, I'm not sure how he did it. ( rack approach parameters? maybe?)

In the Approach Parameters you can set it to move +Z to a specific height before and after a stylus change.

Here I have this system going up 300mm in +Z before it stores and also after it loads. This clears any fixtured parts we have and avoids a direct line to the rack.

Not sure if this is what you are looking for.

Mark Distefano, I have set approach parameters, now I want the clearance plane to always be +Z when running programs.

Have you tried Plan>Navigation>Block Edges and checking the boxes around the sides?

Poor choice of words on my part, I did mean I have trouble with blocked edges. I can never seem to get it to do what I want.

I am hoping others have blocked edges to force a program to move in the +Z clearance plane all the time and could guide me on proper settings.

Attached is a SAB model of the Micura setup. (In ZIP format).

SSC files.

(Odd, the SSC files have more data than the entire CMM with a probe rack).

Bringing this back to life.

I have blocked and blocked edges, can't seem to find the right combination.

Usually all I get is the blocked edges error.

If a Zeiss tech or engineer could chime in. 😁

I don't know exactly how it's named, but i once found that i have checked control for collision or something like that for block edges and that program won't event start - it was immediately an error about crash or something like that.

Look for that - i believe this is it. Should be at same menu as block edges are

I´m not a Zeiss-tech, but have you tried to make the clearance plane in y- that big, that calypso won´t drive thru (like -1000 or something)? Of course then you will have to work with positions in your features, while coming from z+ into the clearance-cube, if you have to measure from y- (but you told above, that you don´t do)

I have limited work area and that is the reason I want to force the CMM to work in Z axis only.

[[Je...]]

I know this problem with limited work area well from my Micuras. To prevent moving in y I make the clearance planes in y big, so the machine allways atomaticly moves into z, when changing from -x to +x or opposite. But mayby I understand you wrong...

I will have to test this, thanks.

All programs on this particular Micura are measured in the X axis or Z axis, but Calypso likes to take the shortest path and that leads to movements in the Y axis.
