3 decimal places?

[TR Mfg.]

Is there a way to change my machine deff so I get only three decimal places?

[Thad]

3 places in the nc file?

 

I would guess it's in the post. Somewhere in the format statements?

3 decimal places for your NC code? Or 3 decimal places for?

It's controlled in the post. Mine is set to 5 decimal places for the Makino's. Maybe someone with post experience can chime in. I can't remember which setting it is.

3 places for the nc code. Why? we are running a large plastic parts in a machine with very little memory and if we drip feed it, it runs slower becouse the buffer is so small. The effect on tolerance this might have is not a concern becouse part tolerance is +/- what ever looks good.

Control Definition - Nc output.

I know it is one of the format statements below. As I stated earlier, output is controlled by the post. I'm sure your reseller can assist you with it.

 

 

#Default english/metric position format statements

fs2 1 0.7 0.6 #Decimal, absolute, 7 place, default for initialize (

fs2 2 0.5 0.4 #Decimal, absolute, 4/3 place

fs2 3 0.5 0.4d #Decimal, delta, 4/3 place

#Common format statements

fs2 4 1 0 1 0 #Integer, not leading

fs2 5 2 0 2 0l #Integer, force two leading

fs2 6 3 0 3 0l #Integer, force three leading

fs2 7 4 0 4 0l #Integer, force four leading

fs2 8 5 0 5 0l #Integer, force five leading

fs2 9 0.1 0.1 #Decimal, absolute, 1 place

fs2 10 0.2 0.2 #Decimal, absolute, 2 place

fs2 11 0.3 0.3 #Decimal, absolute, 3 place

fs2 12 0.4 0.4 #Decimal, absolute, 4 place

fs2 13 0.5 0.5 #Decimal, absolute, 5 place

fs2 14 0.3 0.3d #Decimal, delta, 3 place

fs2 15 0.2 0.1 #Decimal, absolute, 2/1 place (feedrate)

fs2 16 1 0 1 0n #Integer, forced output

fs 17 1.4lt #Decimal, absolute, four trailin

First make backup from your post!

(x:mcamxmillposts*.pst)

 

Locate in your *.pst file XYZ format definitions:

(Here XYZ format type '2')

# NC output Variable Formats

fmt 4 n$ #Sequence number

fmt X 2 xabs #X position output

fmt Y 2 yabs #Y position output

fmt Z 2 zabs #Z position output

fmt IX 3 xinc #X position output

fmt IY 3 yinc #Y position output

fmt IZ 3 zinc #Z position output

fmt A 11 cabs #C axis position

fmt A 14 cinc #C axis position

fmt A 4 indx_out #Index position

fmt R 14 rt_cinc #C axis position, G68

 

 

After locate format definition fs 2 or fs2 2.

 

# Format statements - n=nonmodal, l=leading, t=trailing, i=inc, d=delta

# --------------------------------------------------------------------------

#Default english/metric position format statements

fs2 1 0.7 0.6 #Decimal, absolute, 7 place, default for initialize (

fs2 2 +1.4 1.4l #Decimal, absolute, 4/3 place (Forced +/- sign output)

fs2 3 +1.4 1.4l #Decimal, absolute, 4/3 place (Forced +/- sign output)

 

 

Change +1.4 (or any others) to +1.3; 1.4l to 1.3l !
