Probing

[councill_oak]

We are using a Renishaw H-2000-5000 MP1 Probe with cross-hair pucks on our CMS PF2 for aligning bordered dining room tops and desk tops on the table using 2-point and 4-point cycles. These cycles and cordinates are manually inserted into each program. These cycles are not very versatile causing extensive setup time. I would like to have some cycles that I could incorporate into the post processor so I could pick the cordinates in mastercam and generate the cycle in the program when posting. Most of the information I find is for milling /lathe applications. Help

oak, Look at SL laser projector for this. They will pay for them self in cycle time you are using for probing boarders. I also had a cms with probe & puck. If you are doing ones and twos stick with the puck. But a laser projector is the greatest things for boardered, craped cornered and fancy face tops around.

[Tim Aydt Prototek Engineering]

I created one for a Marposs where I used the Misc. Int's and many many postblocks. The Misc. Int's are filled up, there is no more room to add anything. I think the drill cycle idea is a great idea. Might keep the post a little cleaner looking.

 

A VB Script might kind a cool

[Guest CNC Apps Guy 1]

Tim, that was my first idea but as you said it takees up a lot of MI's and MR's so I opted for the Drilling Cycles. Seeing other's work thouugh has got my propeller spinning for some new things I want to add adnd it looks to be a cleaner way than my way. Thanks for the ideas Craig.

[crazy^millman]

Yeah see some cool ideas there myself. I hope in the near furture we might look into probing and just copied this to my big book of stuff.

[Tim Aydt Prototek Engineering]

James,

[Tim Aydt Prototek Engineering]

James,

I will probably redesign that post based on your's and Craig's ideas.

 

The post works great! The customer doesn't really care how the post looks...but I do. Besides, I have never played with that part of the post before, so I will have to tinker with it.

 

Thanks for sharing the code

 

Tim
