1.43 INTERFERENCE CHECK FOR EACH PATH
T
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.
If such a command that causes tool posts of paths to interfere with
each other is specified, this function gradually stops the tool posts
before the tool posts actually interfere with each other.
The contours and shapes of the tool posts on individual paths are
checked to determine whether or not an interference occurs.
This function enables an interference check between two paths or
interference check among multiple paths. Which check to make can
be determined by parameter setting.
Tool post 2
Tool post 1
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.
Based on the interference forbidden areas of the tool currently selected
on the tool post of each path and tool posts, an inter-path interference
check determines whether the tools and tool posts interfere with each
other, by checking whether those forbidden areas overlap each other
as a result of movement of each tool post. If an interference occurs,
the interfering tool posts gradually stop with an alarm.
