III. G50 through G73
Fun-
ction G Group Meaning Description
Page
G50 16 Programmable
absolute zero
offset * block
Syntax: G50 <axis>
; absolute offset of the machining zero point by the value
programmed using G50 under the address letter for the axis.
3-12
G51 16 Programmable
incremental zero
offset * block
Syntax: G51 <axis>
; incremental offset of the machining zero point by the value
programmed using G50 under the address letter for the axis.
3-12
G52 4 Programmable
workpiece zero
point
* modal
Syntax: G52 <axis>
; A workpiece zero point is programmed using the value
specified at the axis address. All zero offsets which are
already active are canceled
3-13
G53 4 Cancel zero off-
sets
* default, * modal
Syntax: G53
; switch from workpiece coordinate system to mach.
coordinate system.
3-14
G54 -
G59
4 Adjustable zero
offsets * modal
Syntax: G54-G59
; offsets are entered the user interface. G52 or G53 cancels
G54...G59.
3-8
G61 11 Exact stop
* modal
Syntax: G61
; the programmed target position is traversed to
within a specified exact stop limit.
4-10
G62 11 Block transition
with lag * modal
Syntax:
G62 ; sudden contour changes and non-tangential
transitions are rounded off by programming G62.
4-12
G63 16 Rigid tapping
* block
Syntax: G63 <end point> <feed per spindle revolution [F]>
; with G63 the spindle will stop at the end of movement.
4-30
G64 16 Rigid tapping
* block
Syntax: G64 <end point> <feed per spindle revolution[F]>
; with G64 the spindle continues to rotate at the end of the
move.
4-30
G65 7 Floating tapping
spindle as lead
axis * modal
Syntax: G65 <feed per spindle revolution[F]>
; G65 is used to tap threads using non-interpolating main
spindles.
4-34
G66 8 Constant grinding
wheel peripheral
speed
* modal
Syntax: G66 S <Constant grinding wheel peripheral speed>
; Programming G66 causes the programmed S value to be in-
terpreted in m/s or feet/s.
4-44
G70 9 Unit: Inch
* modal
Syntax: G70
; The machine manufacturer defines the base programming
unit in the process parameters.
3-20
G71 9 Unit: Millimeters
* modal
Syntax: G71
; The machine manufacturer defines the base programming
unit in the process parameters.
3-21
G72 18 Mirror function
OFF
* default, * modal
Syntax: G72
; the mirror function is canceled in all axes.
3-22
G73 18 Mirror function
ON
* modal
Syntax: G73 <axis name>-1
; the coordinates of the axes entered in the axis name are
mirror imaged.
