20.5 HSC FAST mode. Optimizing the machining feedrate.
In spite of the recommendations for generating CAM programs, it is possible to have
programs already generated that do not show a continuity between the error generated by
the CAM, the block size and the error required by the HSC. For this type of programs, the
HSC mode has a fast mode where the CNC generates paths trying to restore this continuity
and thus be able to work on a smoother surface and obtain a more continuous feedrate.
Programming.
Program the instruction alone in the block. This mode is turned on with the instruction #HSC
ON and the FAST command.
Programming format.
The programming format is the following; the arguments appear between curly brackets and
the optional ones between angle brackets.
#HSC ON [<FAST> <,E{error}> <,CORNER{angle}> <,RE{error}> <,SF{frequency}>
<,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.
Programming the chordal error improves the accuracy in curved segments or circles;
however, and considering the peculiarities of executing in FAST mode, the contour error at
the corners is not ensured.
FAST 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
SF{frequency} Optional. Path filter frequency for linear slope.
Units: Herz.
AXF{frequency} Optional. Axis filter frequency.
Units: Herz.
#HSC ON [FAST]
(Chordal error = machine parameter HSCROUND)
(Angle = machine parameter CORNER)
(RE error = machine parameter MAXERROR)
(SF filter = machine parameter SOFTFREQ)
(AXF filter = machine parameter FASTFILTFREQ)
#HSC ON [FAST, E0.05]
(Chordal error = 0.05)
(Angle = machine parameter CORNER)
#HSC ON [FAST, E0.01, CORNER130]
(Chordal error = 0.01)
