Programing Example

The examples below show the influence of the different output of M functions during contouring.

N907090              X0 Y0

G91 G01 F6000

N01 #CONTOUR MODE [DEV PATH_DEV=10 POST_ACTION]

N10 X100 G61 M25    (MVS_SNS)

N20 Y100 F3000

N30 X100 G61 F6000

N40 G04 X2

N50 Y100

N00 X0 Y0

N60 X100 G61

N70 Y100 M26        (MVS_SVS)

N907091 G04 X1

Output before the contouring curve:

N01 #CONTOUR MODE [DEV PATH_DEV=10.0 PRE_ACTION]

Output within contouring curve:

N01 #CONTOUR MODE [DEV PATH_DEV=10.0 INTER_ACTION]

Output after contouring curve:

N01 #CONTOUR MODE [DEV PATH_DEV=10.0 POST_ACTION]

If the acknowledgement of M25 is delayed by block N10, the motion is stopped after the contouring curve and the program waits for PLC acknowledgement.

Programing Example

Change the limit angle during contouring:

#CONTOUR MODE [DEV PATH_DEV=0.50 RELEVANT_PATH=0.1 TRACK_DEV=2 RELEVANT_TRACK=0.2]

F10000

G261

N5 #CONTOUR MODE [MAX_ANGLE=3]

N10 G01 X0 Y0 Z0 G61

N15 #CONTOUR MODE [MAX_ANGLE=4]

N20 G01 X100 Y0 Z0

N25 #CONTOUR MODE [MAX_ANGLE=5]

N30 G01 X100 Y100 Z0

N35 #CONTOUR MODE [MAX_ANGLE=6]

N40 G01 X0 Y0 Z0 G61

G260

Result:

Contour the N block always takes place at the limit angle of the previous N<i-5> block.

Programing Example

Variation of the contour angle with constant limit angle:

#CONTOUR MODE [DEV PATH_DEV=0.50 RELEVANT_PATH=0.1 TRACK_DEV=2 RELEVANT_TRACK=0.2]

#CONTOUR MODE [RELEVANT_TRACK=0.3]

P100 = 50

F10000

#CONTOUR MODE [MAX_ANGLE=73]
