WEIHONG NK280B - Parameters for QEC

NK280B Parameter Reference
Table 9: Parameters Related with Prompt
Parameter Name Description
Enable Workpiece Compensation If the parameter is set to Yes，the system
will ask you to confirm whether to continue
machining with workpiece compensation
enabled when you start machining.
Prompt for Public Offset Saving Whether to give prompt when clearing
coordinate to zero. If it sets to "True", prompt
the user to save the public offset or not; else
directly save the public offset without prompt.
Parameters for QEC
Parameters that will influence the use of QEC (Quadrant Error Compensation) function.
When machining an arc, use QEC function to make compensation for the acute angle to get
smooth result.
For details about QEC function, see NcStudio Function Manual.
Table 10: Parameters Related with QEC
Parameter Name Description
Enable Quadrant Compensation Whether to enable cross quadrant
compensation function for the acute angle.
Quadrant Compensation Time The larger value is, the larger the
compensation-affected area will be.
Recommended value: 0.02s.
Quadrant Compensation Value The larger its value is, the more obvious
the compensation result will be. However,
note that too large value will make the arc
concaved, while too small value will not
suppress the spike effectively. It is suggested
to measure the actual height of the spike with
a laser interferometer or other measuring
device in debugging, and then set this
parameter as 0.3 to 3 times of spike height.
Compensation result is also related with
compensation time and intensity.
