POST QUESTION

[FUSION]

For you post gurus out there , what should the line look like in the " End of File for non zero tool " block , to omit a tool change command if there is only one tool in the program? I know it should be a formula statement but I'm a beginner here so bear with me. Thanks.

Essentially you want to set up a tool counting mechanism. Once you do that then you can say something like the following;

 

if tool_count >1, go here,

else,

...

The tool counting mechanism would have to be in the pwrtt postblock, and would look something like this:

 

if t>0 | t <> prv_t, tool_count = tool_count+1

!t

 

You will also need to make sure your tool number is forced in the psof postblock, i.e. it should read *t.

 

Actually, it can be done simpler than the above, if you just need to know whether there is more than one tool, but if you also need to preselect first tool or an empty pocket at the last toolchange, then the above code is the way it should be done, to ensure correct output if the same tool is used more than once in a program.

Also if bldnxtool is initialized to 1, you can use a pre-defined variable called ntools that acts as a tool counter.

Dave, what happens with the ntools variable if a given tool is used more than once in a program? I have not tried to use the ntools variable myself, as I know the method I use works. "If it isn't broken, don't fix it" is good advice to anyone.

[Allan Brown]

I totally agree Christian, and actually use a method like yours myself. Just offering up an alternative!

 

Looks like ntools counts full tool changes.

 

op1 T1, op2 T1 - ntools = 1

op1 T1, op2 T1, op3 T2 - ntools = 2

op1 T1, op2 T1, op3 T2, op4 T1 - ntools = 3

even easier,

if t = t,e
