Fig. 6.3 (c) Creating or changing the forbidden area using a parameters
In stored stroke check 2, even if you mistake the order of the coordinate
value of the two points, a rectangular, with the two points being the
apexes, will be set as the area.
When you set the forbidden area through parameters (Nos. 1322, 1323),
the data should be specified by the distance from the machine coordinate
system in the least command increment. (Output increment)
If it is set by a G22 command, specify the data by the distance from the
machine coordinate system in the least input increment (Input increment.)
The programmed data are then converted into the numerical values in the
least command increment, and the values are set as the parameters.
Set the boundary with parameters No. 1324 and 1325. The area inside the
boundary becomes the forbidden area.
Confirm the checking position (the top of the tool or the tool chuck) before
programming the forbidden area.
If point A (The top of the tool) is checked in Fig. 6.3 (d) , the distance “a”
should be set as the data for the stored stroke limit function. If point B
(The tool chuck) is checked, the distance “b” must be set. When checking
the tool tip (like point A), and if the tool length varies for each tool, setting
the forbidden area for the longest tool requires no re–setting and results
in safe operation.
