Programming issues

[Mike Riffel]

We are quite new with PC-DMIS (not trained yet) and have a question when developing a program. We measure the feature and then deactivate the probe until moved to the next feature then reactivate it. The program will not work in this senario. We found that if we leave the probe activated the program will work. Can you deactivate the probe and move it or does it need to stay activated through the entire program?

welcome-good luck

Hello Mike,
Welcome to dmis land. I am not sure I understand what you are doing. Are you using the "probe enable" button on the jogbox to unenable the probe or some other method? What kind of probe, (tp2, tp20, tp200, sp25, etc)? Why are you disabling it at all? Are you trying to prevent air triggers? What type of machine are you on? Browne & Sharpe, Wenzel, etc. To answer your question as best I understand it: No I usually leave the probe active the entire time I am programming. HTH

[Mike Riffel]

We have a TP20 on a DEA machine. We are using the handheld controller and disabling the probe to move quicker from feature to feature (it saves us some time especially on bigger parts).

*Do not Deactivate the Probe* This is a situation with all of the cmm's that I have been associated with. All you can do is: Change the move speed to 100 %. This would be under the pref, motion option.

In reply to your "We're new to programming" statement, I must ask this question... When coming out of the measured diameter are you then inserting a move point where you want the probe to move to? If this is the case then you can either use the toolbar to insert a move point or "ctrl+m" will do the trick as well. Not trying to insult your intelligence or anything it was just something I thought of if you guys are as green as you made it sound...

The only time I ever disable the probe is when I'm manually changing TP-20 modules and even then it isn't really necessary.

Don't use move points us clearplanes

[Bill **********]

Either move points or clear planes are fine do as you feel is best for your situation. Personally I never use clear planes because of the shapes of the majority of the gages that I measure. It just forces me to put in HUGE clearance planes which waste a bunch of time. I use FLY mode and move points which runs about twice as fast as clear planes for my situation.

I'm with ya bill, I took the PCDMIS class in nashville a few years ago. They preached clear planes. since we measure funky shaped stuffs its really not very usefull. Though in the classroom on the excersize block it rocked

I didn't know that enabling and disabling the probe on the jog box would speed the probe up. I would think that during an auto program you wouldn't want to mess with anything at all. INSERT/PARAMETER CHANGE/MOVE SPEED and crank up your speed. I would think that you'd run into problems turning the probe on and off manually? Never done it - don't know?

[John Kugler]

On our Mituyoyo we have whats called a measure button. When it is not on, maually the probe zips along pretty good, but hits do not register. When it IS on the probe moves quite slow and probe hits register. This is NOTHING to do with the software, all in the controller.

Is this similiar to what you have??

Software wise, when a program is running in DCC, THEN all the paramaters take over and probe moves like it should.

[Mike Riffel]

Yes, this is exactly how ours works. We just thought we developing a program you could speed the process up by disabling the probe and move faster between features or even hits being taken on a feature. thanks

I have seen that option in Pcdmis (ignore motion errors) in the F5 set-up page. HOWEVER, I will NOT use that option. It will ignore any triggers of the probe when the machine is executing any kind of a move but NOT when executing a 'touch'. So, what happens when you (or your co-worker) puts in an incorrect clearance plane value? The machine keeps moving throught the crash until it gives an error of a different sort. Like, "You have just smashed your PH9 and torqued your machine out of square because I tried to drive through the fixture but I was ignoring the motion errors like you wanted me to. Please pay $1000's for a new head and $1000's more for a new laser calibration of the machine since I am now bent like a pretzel." Man, I hate when THAT error comes up! Is the extra 10 seconds you save worth all that?

If you want more speed. Go into INSERT/PARAMETER CHANGE/MOVESPEED, you can change that to 100% if you wish.

On the diameter question. Click on the ADVANCED button, the menu will unfold, at the bottom where it says MOVE (drop down menu), DISTANCE. Enter your value in inches/mm how far to move, and choose in the MOVE menu NO, BOTH (before and after), etc.

Man, I' glad I've NEVER seen that error yet! Kinda like drilling for oil? Heck, just a bassackwards vector from a clearence plane could get that situation goin' real fast with the ignore motion errors enabled.
Myself, I like move points. Got weird forms, verticle walls, flanges and so on. Simpler & faster just poppin' in a few move points here and there. And it sure beats watchin that head yo-yo all over the place 'til the programs done.
