Need Help!- Hit Tool Offset Measure by accident

[fuzzyracing1967]

I don't use a probe so didn't know that turning 119 on would still not help there.However correct me if I'm wrong,after you get your work offsets and tool offsets useing the probe on that first peice you no longer need to probe any additional parts or tools affter that? Or are you guys probing every part you run even if there just like that first one? The reason I ask is, after that first part you can turn on 119 on and it wouldn't matter becouse there would be no reason to probe anything untill you wanted to make differant parts.Have to ask becouse I'm old school if you will .

Fuzzy,

I only use the probe for my initial set-up. I do how ever see a need on some parts like casting where I might probe each part do to core shifts. So far my castings have been consistant enough where it hasn't been an issue yet.

Thanks again for the tip on setting 119, I am going to be leaving it on most of the time.

One other note with the probe with tools. Once your tool is set you do not have the set again, unless you remove it from the holder.

Most of the parts going through my mills are castings, the trick to getting consistant parts is having your stops where there is no grinding from the foundry.Actualy today I could have used one of those probes becouse we had some parts that went to the sl30 first and then to my vf4.I made stops right on a set of jaws to oreant the parts on the indexer,only problem was the parts weren't consistant from the sl30,so I had to change the a work offset for damm near every part.However going back to your original problem,is there a way to use those probes that you would get negative tool offsets? I only ask becouse then an acedental push of the tool offset button wouldn't mean a crash like you had.

Turning 119 on does help here. This way I can still use the probe to set tools and work offsets, but you can not make manual changes to the offsets on the control panal. I will only have to turn it off if say I am indexing the A axis where I can't use the probe, or lets say I have to shift X over .100 it will not allow you make those changes. So it might be a pain to have to go to settings and turn it off every time I need to make a change, but its a lot better then crashing. The positive tool numbers don't bother me so much now that I understand them more and I can lock the offsets to avoid accidental changes.

I've had machines with a button protector, that didn't allow you to press a certain button until you flipped up the protector, so accidents like resetting a tool length never happens unless you WANT it to happen.

And the first time you forget to re-lock it will be the time you accidentally hit the button; Murphy rules you know.


I think even with the offsets locked with Setting 119 you can still enter values from a program using a G10 command. So you do not need to unlock, just type the G10 line in MDI and press cycle start and the change will be done.

mmk firstly the pendant has 2 buttons one is spindle jog the other is cycle start, a pulse wheel and a resolution selection knob unless they have changed since 05'. for the guy who doesnt like them i would love to see him tram a part using a .0005 last word indicator in on a VF-12 without it unless you use binoculars. setting 119 "offset measure uses work" this means that your tools will be measured in relation to Z-zero in whatever offset you are using (G54-G59 or G110-G129)and will measure negative geometry, (the distance from the spindle to the tip of the tool) when this setting is off you are using the Rennishaw tool probe and the setting values established for the probe height are compensated for and tools are measured relative to machine zero rather than work shift zero (the distance from the table to the tool tip at z home) therefore tools will be measured positive geometry. IE: Using probes = setting 119 off Using old school shimstock off the table or part = setting 119 on. you really only need this setting on of you have broken your probes and have to resort to archaeic old school practices to get your machine running. why your tool crashed after hitting tool offset measure is beyond me unless someone changed this setting from off to on while you werent looking the G54 would be shifted the distance from part zero to the top of the probe. or someone slipped in a nasty little G91 move. Try putting a G53 before each M01 to clear the previous offset system before calling up a new oneor or you accidentaly hit the axis jog lock and the machine picked up the preset indexed moves established in the advanced jog coordinate system.....sometimes info gets jumbled in the processor buffers and will either hold or drop offset data from time to time (otherwise known as gremlins) the best way to avoid this is by hitting the reset key as often as practically possible. I belive The newer controll will allow you to remeasure tools from the current comands screen. let me know what HAAS has to say, I can usually give those guys a run for thier money but its still curious.
