drilling conditional test

[Craig Madsen from CM3D]

So, I have a condition where I need to NOT output a spindle speed, M03, and Coolant on when using a custom drill cycle #9.

 

 

 

Here is the code I have:

 

pcan1, pbld, n$, *sgcode, sgplane, [if not(index), sgabsinc, pwcs], [if gcode$ = 1, sgfeed], pfcout, pfxout, pfyout,

[ if not(opcode$ = 3 & (drillcyc$ = 9)), pfspindleout], [if gcode$ = 1, *feed], strcantext, e$

 

 

 

Which I think SHOULD output 'pfspindleout' anytime EXCEPT when outputting a opcode$ = 3 AND drillcyc$ = 9.

But, what I find is that during the toolchange cycle, while opcode$ does equal 3, the drillcyc$ is 1.

 

 

How do i get the drillcyc$ to be what is called out in parameters during the toolchange? It is correct during the rest of the program, just not at program start, or toolchange.

 

 

 

Thanks

an example where drillcyc$ SHOULD BE 9, but isn't:

 

N1590 G0G90G17G54X-27.0Y22.

N1600 T22 M06 (9/16 STERLING GUN DRILL)

N1610 (MAX - Z.1)

N1620 (MIN - Z-7.45)

GOT HERE !!! opcode$ 3. drillcyc$ 1. (Printing opcode$ and drillcyc$ status)

N1630 G00 G17 G90 G55 X-4.25 Y0. S407 M03 (S407 M03 should not be output)

N1640 G43 H22 Z.1 T11

 

BUT, at the beginning of the program, where Drillcyc$ should be 2, it posts as:

 

N130 T9 M06 ( LTR. U GARR CARBIDE DRILL)

N140 (MAX - Z.1)

N150 (MIN - Z-1.086)

GOT HERE !!! opcode$ 3. drillcyc$ 9.

N160 G00 G17 G90 G54 X0. Y4.5

N170 G43 H9 Z.1 T11

N180 G94

N190 G98 G83 Z-1.086 R.1 Q.25 F1.02

 

I figured I would print examples of output - It has me stumped.

To look ahead in the NCI file, you need to make sure the pre-defined variable 'getnextop$' is enabled (set to a value of '1').

 

This creates a table of "next variable values" that you can access.

 

Once the 'getnextop$' has been enabled, you can use the pre-defined variable 'nextdc$' to get the value of the next Drill Cycle.

 

At Toolchange, the 'nextdc$' variable should have a value of the Drill Cycle you set in the Toolpath Operation.

 

Keep in mind that the 'drillcyc$' variable uses an index of '0'. So a 'Simple Drill' routine is a 'drillcyc$' value of '0'. Peck is a 'drillcyc$' value of '1'.

 

So if you are using Custom Drill Cycle #1, the value is '8'. If you are using Custom Drill Cycle #2, then the value would be '9'.

 

Hope that helps,

To simplify your code a little bit, you could probably write your logic like this:

 

pcan1, pbld, n$, *sgcode, *sgabsinc, pwcs, pfxout, pfyout, pfcout,
       [if nextdc$ <> 9, pfspindleout], pgear, strcantext, e$

Colin,

 

 

nextdc$ worked perfectly. Thank you, very much.

 

 

getnextop$ was already set - but I wasn't using nextdc$.

 

 

Thanks, again.

Glad it worked for you Craig.
