20.4 HSC CONTERROR mode. Optimizing the contouring error.
From this instruction on, the CNC modifies the geometry through intelligent algorithms for
eliminating unnecessary points and automatically generating polynomials. . This way, the
contour is traveled at a variable feedrate according to the curvature and the programmed
parameters (acceleration and feedrate) but respecting the set error limits.
Programming.
Program the instruction alone in the block. This mode is turned on with the instruction #HSC
ON and the CONTERROR command.
Programming format.
The programming format is the following; the arguments appear between curly brackets and
the optional ones between angle brackets.
#HSC ON [<CONTERROR> <,E{error}> <,CORNER{angle}> <,RE{error}>
<,AXF{frequency}>]
HSC mode.
The work mode must only be selected when it is not the default mode (parameter
HSCDEFAULTMODE).
Maximum chordal error allowed.
The E command sets the maximum contouring error allowed between the programmed path
and the resulting path (mm or inches). This command is applied to the first three linear axes
of the channel. Programming it is optional; if not programmed, the CNC assumes as
maximum contouring error the value set in machine parameter HSCROUND.
Maximum angle for square corner.
The CORNER command sets the maximum angle between two paths (between 0º and 180º),
under which the CNC machines in square corner mode. Programming it is optional; if not
programed, the CNC assumes the angle set in machine parameter CORNER.
CONTERROR Optional. HSC mode.
E{error} Optional. Maximum chordal error allowed.
Units: mm or inches.
CORNER{angle} Optional. Maximum angle for square corner.
Units: from 0 to 180º.
RE{error} Optional. Maximum error on rotary axes.
Units: Degrees
AXF{frequency} Optional. Axis filter frequency.
Units: Herz.
#HSC ON [CONTERROR]
(Chordal error = machine parameter HSCROUND)
(Angle = machine parameter CORNER)
(RE error = machine parameter MAXERROR)
(AXF filter = machine parameter HSCFILTFREQ)
#HSC ON [CONTERROR, E0.01]
(Chordal error = 0.01)
(Angle = machine parameter CORNER)
#HSC ON [CONTERROR, E0.01, CORNER150]
(Chordal error = 0.01)
(Angle = 150º)
#HSC ON [CONTERROR, CORNER150]
(Chordal error = machine parameter HSCROUND)
(Angle = 150º)
