WinPC-NC Economy Parameter settings
The possible units are millimeters and inches. HPGL files are usually
in units of 1/40 mm or 1 mil, while drilling data are usually in 1/100
mm or also 1 mil. EPS and AI files are in 1/72 inch.
Units in the program
The UNITS parameter defines the units for dimensions and speeds
used in the graphical display and the parameters.
It is possible to select between three options :
• Millimeters and millimeter/second (mm and mm/s)
• Millimeters and millimeter/minute (mm and mm/min)
• Inch and inches/minute (inch and inch/min)
Sensor dimension
Measuring
Z-axis heights
automatically
WinPC-NC can automatically measure different Z-axis heights using
a sensor block (surface block). The sensor block outputs a signal
when it is contacted from above, and the signal is processed as an
input at the LPT port.
The measuring procedure involves several steps:
1. Place the sensor block on the workpiece surface or on the machine
bed for the maximum Z-axis depth.
2. Move the tool over the sensor block in jog mode.
3. Start the measurement using the MOVE-JOG menu function.
4. WinPC-NC slowly moves the tool down to the sensor and stops
when it makes contact. The position is checked and added to the
defined sensor dimension, the result being stored as a parameter.
