8.3 PATH INTERFERENCE CHECK
T
Overview
When tool posts on individual paths machine the same workpiece
simultaneously, the tool posts can approach each other very closely.
If the tool posts interfere with each other due to a program error or any
other setting error, a serious damage such as a tool or machine
destruction can occur.
The function "path interference check" decelerates and stops the tool
posts on individual paths before they actually make contact with each
other if a command is issued and they will interfere with each other as
the result.
Bit 7 (IFP) of parameter No. 8140 can be used to specify whether to
make a two-path interference check or multipath interference check.
Tool post 2
Tool post 1
The contours and shapes of the tool posts on individual paths are
checked to determine whether or not an interference occurs.
Explanation
- Data Setting for the Path Interference Check Function
To make a path interference check, data including the relationships
between the tool posts on individual paths and interference forbidden
areas (that is, tool shapes) needs to be set. The method of such data
setting is described below.
