5.5 Polynomial interpolation (POLY, POLYPATH)

Deactivates the polynomial interpolation for all axes

N10 G1 X... Y... Z... F600

N11 POLY PO[X]=(1,2.5,0.7) ->

-> PO[Y]=(0.3,1,3.2) PL=1.5

N12 PO[X]=(0,2.5,1.7) PO[Y]=(2.3,1.7) PL=3

N20 M8 H126 ...

N25 X70 PO[Y]=(9.3,1,7.67) PL=5

N27 PO[X]=(10.2.5) PO[Y]=(2.3)

N30 G1 X... Y... Z.

Example of applicable polynomial syntax with PO

Polynomial syntax used previously remains

PO[axis identifier]=(.. , ..)

PO[PHI]=(.. , ..)

PO[PSI]=(.. , ..)

PO[THT]=(.. , ..)

PO[]=(.. , ..)

PO[variable]=IC(.. , ..)

Example of a curve in the X/Y plane

;Polynomial interpolation ON

;Mixed settings for axes

;No PL value programmed; PL=1 applies

;Polynomial interpolation OFF

;New polynomial syntax (SW 6 and higher)

;Axis identifier=PO(.. , ..)

;PHI=PO(.. , ..)

;PSI=PO(.. , ..)

;THT=PO(.. , ..)

;PO(.. , ..)

;variable=PO IC(.. , ..)
