General Mach Discussion / Re: Tool Change

« on: January 03, 2008, 04:45:55 PM »

I do not see the big problem in entering 3 words 'G43 T1 M6' for each tool used, this call sets the height offset and loads the diameter offset ready for use by G41 or G42.

One of the reasons Mach works this way is so that tools can be pre-selected by calling T2, then the tool changer is ready for changing by the M6 command

As far as I know you can only have 4 axis displayed at any one time.

Not sure about some parts of your code, e.g. G53 expects a X and Z as a distance from zero return, G28 also expects a X0 and/or Z0. 

This is how I would do the code :-

At the end of each tool, after it rapids to tool change position insert Tnn00, this cancels the last tool offset. nn is the tool number in use.

There are a few bugs it turn, this may be one of them.

It would appear there are a few issues with comp and front/rear turrets. Brian has it on his to do list now, so it will get sorted.

Here is a non G42 version for you to try.

« on: December 31, 2007, 08:55:11 AM »

Ok, this is how I would do the first op.

Datum is on left hand end for X axis.

Y and Z axis are on indexer centre line.

Using a 1/8" end mill.

I would try it on a bit of wood or plastic first.

Material is 1.375 square or round, by length of job plus what ever length you need to clear the indexer with the head.

I think you need to re-think your machine or look at using a Fanuc 18Mi they are only 13 axis and $20000.
