Parameter
Function Settings
MC_1004:
Circle adjustments
Specifies whether circle centers or
endpoints will be adjusted. Circle
centers require adjustment when the
CNC encounters incorrect circle center
or end-point coordinates.
Center - Adjusts the position of the
circle center when the CNC
encounters incorrect
coordinates for either a circle
center or endpoint.
End-Point
- Adjusts the position of
the circle endpoint when the
CNC encounters incorrect
coordinates for either a circle
center or end-point. [Default]
MC_1005:
Circle centers
Switches the default mode for
programmed circle center coordinates.
Absolute - CNC interprets
programmed circle center
coordinates as Absolute
values.
Incremental
- CNC interprets
programmed circle center
coordinates as Incremental
values. [Default]
Modal - CNC interprets
programmed circle center
coordinates based on current
Incremental or Absolute
setting.
MC_1006:
Maximum arc
correction
Specifies the maximum amount of
correction the CNC will apply to an arc
block before declaring an error.
Range (0.000000–1.000000)
0.005000 [Default]
MC_1007:
Internal accuracy
Maximum accuracy available (system
resolution).
Range (0.00000001–0.00100000)
0.00000100 [Default]
MC_1008:
External accuracy
Specifies the maximum system
accuracy obtainable on a given machine
(machine resolution).
Range (0.00000001–0.00100000)
0.00010000 [Default]
MC_1009:
Compensation cutoff
angle
Minimizes wasted travel on acute angle.
Refer to
Range (1.0–90.0)
15.0 (degrees)
[Default]
MC_1011:
User macro file
Specifies macro filename created by
user.
USERCANN.G [Default]
MC_1012:
