Abstract
When an operation state of a numerical controller which controls a machine tool is (1) in a state were rotation of a spindle is being stopped, (2) in a state where cutting feed rate of a tool with respect to a work exceeds a set maximum cutting feed rate corresponding to a work material, or (3) in a state where the tool moves in a direction different from the work cutting direction of the tool, it is checked whether or not the tool and the work interfere with each other. In other operation states, an interference check is not executed.
Claims5
A numerical controller having an interference check function comprising:
- an interference check executing unit which checks interference between a tool and a work;
- an operation state setting unit for setting an operation state of the numerical controller which controls a machine tool in which said interference check executing unit is allowed to execute an interference check;
- and
- an execution determining unit which causes the interference check executing unit to execute an interference check when an actual operation state of the numerical controller which controls the machine tool coincides with an operation state stored in the operation state setting unit, but does not allow the interference check executing unit to execute the interference check when the actual operation state does not coincide with an operation state stored in the operation setting means.
