Tool setting....?
« on: April 08, 2011, 01:38:31 AM »
I need to get something to do tool setting. I have a tool changer and I think it would be better than trying to do it manually.

Should I get one of these dedicated to tool setting?

Or should I get something else, and what would it be?

Basically I want to buy a tool setter and a touch probe, and I want to know my best bet.  I dont want to use either as dual purpse do to setup and the constant need for each.

They dont really say how accurate these are or if one is better than the other, or maybe I should get something else for tool setting?

Do a search for Auto tool zero
Lots of people are just using a pice of copper clad pcb board.

Yeah I seen those posts. How accurate is that though and is there risk to damaging something since there is no "spring" area? Is there any advantage to using the actual tool setter vs the copper clad pcb?

As long as the approach is slow there is no problem with tool damage and copper clad board. The probing script stores the exact touch point whilst the axis drive is stopped, the overrun is only a thou, perhaps less and the surface of the copper clad takes this easily, Mach then returns the axis to the touch point plus whatever you have chosen for tool clearance so the accuracy is good. The probing script has to be right though, there is no room for error (spring loaded stuff) but, I haven't broken a 1mm endmill yet (but tomorrow is another day and who knows ?  ;D )

You use a laser Tweakie, you can't break end mill ;D ;D ;D

The probe from IM is great, I like it so much I have two, 1 for tool setting and 1 for probing (the tool does both, but takes time to switch physical setup).

I keep the probe in a toolholder and have it in the tool table for everything from probing to just finding an edge.

The toolsetter is great if you break a tool mid job, 2 minutes or less and your back to chips :)

I think it's on sale?

nice people too.....

I bought two of the ones from Wildhorse. I will also use one as a tool setter and the other as a probe. Two of those is still less than one of the IM ones. I am not sure if the IM is any better?

I use a circle of PCB material, mounted by its edge.  So, when Mach's probing routine loses its mind (which it sometimes does), and tries to drive the tool through the PCB, the PCB just breaks, and I put in a new piece.

If you use tool holders with some kind of a reasonable reference surface (i.e. - CAT, ISO, etc.), you can just use a simple height gauge.
