Maximum error on rotary axes.
The RE command defines the error in all the rotary axes and linear axes (except the first
three axes of the channel). Programming it is optional; if not programmed, the CNC assumes
as maximum error the highest value between machine parameter MAXERROR and the E
command.
Axis filter frequency in HSC mode.
The AXF command allows applying different filters to those set in the machine parameters.
Programming it is optional; if not programmed, the CNC assumes as maximum contouring
error the value set in machine parameter HSCFILTFREQ.
Considerations.
Commands E and CORNER.
The CNC maintains the value of the commands programmed until a different one is
programmed, the HSC mode is canceled, a reset is done or the program ends.
When switching HSC modes, the CNC keeps the values programmed in the previous mode
for the commands that are not programmed (for example, the contouring error). If no HSC
mode has been programmed earlier, the CNC takes the default values for the commands
that are not programmed.
Commands RE, SF and AXF.
The CNC maintains the value of the commands programmed until a different one is
programmed, the HSC mode is changed or canceled, a reset is done or the program ends.
When changing HSC modes, the CNC assumes the default values set in the machine
parameters.
Execute an HSC mode starting with initial conditions.
To execute in HSC mode starting with initial conditions, first cancel the previous mode. See
"20.6 Canceling the HSC mode." on page 374.
Example 1.
#HSC ON [CONTERROR, E0.050]
·
#HSC ON [SURFACE]
(Chordal error = 0,050)
Example 2.
#HSC ON [CONTERROR, E0.050]
·
#HSC OFF
·
#HSC ON [SURFACE]
(Chordal error = machine parameter HSCROUND)
