setting counter to count more than one

[CNC-Hammer]

Hiya,

will the MB56VA recognise a command such as G10 Pn Rn?

where P is the offset number and R is the multiplier.

In other words will the control add n to offset n everytime it is read?

So if I was doing four parts to a cycle the control would count four each time the cycle stops.

I hope this makes sense....

yes Okuma can do this. the following exanple uses tool length offset number 10 and adds 1mm

VTOFH[10] = VTOFH[10]+1

Excellent, can the same be done using a diameter offset rather than length offset?

[budgieW]

Yes

VTOFD[10] = VTOFD[10]+1

Thanks for the advice, I figured out the diameter one after asking.

I tried both on the machine but it would not add to the counter each time it was read. It would only set the counter to 2, so an absolute rather than incremental value.

You could also use the user variables to actully preset or check the count

ie
VC1=VC1+4

Um what counter are you talking about here? I have no idea what G10 R P does so you may need to explain what it is you are actually trying to do here.

Yeah I was thinking along this line but I have never used macros or variables so wouldn't know where to start.

On a Fanuc control G10 P32 R1 will add 1 every time it is read to offset 32 so it can be used as a counter. To count in multiples just change the R value to how many is required per cycle. So if four parts per cycle were completed the line would be G10 P32 R4.

I was just trying to replicate this on an Okuma.

Ok Now I see there are a few options here

1 - Write a little loop program

DEF WORK[1]
DIREC V
ORIGIN H1
CYLNDR 2P,[-50,-50],[50,50],-20,0
CYLNDR 0H,[0,0],38,-20,0
END
DRAW

T10
M6
VC1=0
G15H1
Z100G56H=VATOL

NLOOP
X0Y0S100M3F1000
Z10
G1G41D=VATOLX20Y0
G3 I-20 Z2
G3 I-20 Z4
G3 I-20 Z6
G3 I-20 Z8
G3 I-20 Z10
G0 Z10
VC1=VC1+1
VTOFD[10] = VTOFD[10]+1
IF [VC1 LT 4] NLOOP

G90G0G40X0Y0
Z100
M2

2 - COPY function may also be usefull

DEF WORK[1]
DIREC V
ORIGIN H1
CYLNDR 2P,[-50,-50],[50,50],-20,0
CYLNDR 0H,[0,0],38,-20,0
END
DRAW

T1
M6
G15H1
Z100G56H1
X0Y0S100M3F1000
Z-20
G1G41X20Y0D1

COPY Q10

G91 G3I-20 Z2

COPYE

G90G0G40X0Y0
Z100
M2

So, going by your 1st post
You wish to do a parts count when the program makes (4) parts per cycle ?

What control does it have ?

Hey Greg, you still OS ?? LOL

[CNC-Hammer]

Hey thanks but I was after purely a counter. It appears what you have posted is a 'subprogram' to repeat a section of the program.

I often use the copy command but I've not seem the NLOOP command before, but then I've not long started using Okuma.
