Tool Numbers In Lathe
« on: May 31, 2010, 01:19:16 PM »
What is the maximum amount of tools you can use in lathe

The tool table has 250, i don't have that many but want to make it easier to use the tools with different inserts.

So for instance tool 03 would be .4mm Radius tool 103 would be .8mm Radius

If i put tool 103 in the tool number DRO it gives that detail on screen

I lack the courage to try it in code.  ::)

99 tools 99 offsets.
If you call T103 from code you will get Tool 1 Offset 3.

Hood Thanks

I thought that was the case, i tried a search but came back with no results.

So being pedantic, the tool table is in fact 99 offsets which holds all the tool offset details

The 99 tools are just numbers that have no info attached to them ?

From posted replies here is what is currently in Appendix F of the LazyTurn manual.

6.1 TOOL TABLE
As of this writing or until Mach3 Turn is updated a few comments are noteworthy:

1.Do not use front and rear tools definitions for your tools. Choose one or the other but not both.
2.I don’t recommend using the other settings such as tip direction, diameter, and wear offsets. Frankly, I have never used them and not sure if they are buggy, but irrelevant you won’t be using them because of pre compensated code.
3. The tool table lists 253 tools, but you can only use 99 of them because of the
           the tool numbering format in Mach3 Turn is based on industry standards of 99
           tools.
 4. Tool “0” is not accepted as a call out in some programs.
Lathes use the format TAABB to define the tool number and the offset.
AA is the tool number – T01 to T99
BB is the offset number – TAA01 to TAA99

The offset can be associated to a tool. IE; you have 9 tools with a specific offset based on the tip radius as follows:
T0101
T0202
T0303
T0404
T0505
T0606
T0707
T0808
T0909
Then you can also have another set based on center line of the tip radius by just manually changing the number and adjusting the offset by the radius in the tool table as follows:
T2001 or T0111 or T0121
T2102
T2203
T2304
T2404
T2505
T2606
T2707
T2808
T2909

The user would know that series “T20 –T29 are to be used for LazyTurn. Same tool just
a different offset. All that really matters is that the user have some kind of logic so the proper tool is defined in the LazyTurn Tool dialog. This would not require modifying the original tool offsets and allow for the use of the same series of tools to be used with a different offset.

The controller ( Mach3Turn) applies offsets in strict order so first part offset, then the program offset, then the tool offset and other modifications as defined by the program.
( confirm order )

You being pedantic, no way, I would never  believe that ;D
Seriously though, yes the tool table is really an offset table

The 99 tools are just numbers that have no info attached to them ?

The tool numbers are really only of use if you are using a tool changer of some sort as your tool change macro will need to know which tool position to rotate to. You still have to call the tool number however as Mach will not accept it if not but you could always call Tool1 with any of the 99 offsets and it wouldnt matter.

OK thanks for the answers.

It seems a certain way to confuse and get a crash

For now i have solved the problem by adding 30 to tools with a different insert so T0303 becomes T3333 with a different insert

Yes I do the same, have 10 tool positions total in my Turret and Toolpost so I have T01 to T10 and offsets for each slot are 01 to 09.
Going to be screwed if I ever manage to get the front turret fittet as that will be 12 tools total LOL
