More Information
Summary:Disclosed is a numerical controller capable of foreseeing the occurrence of interference during operation of a machine and securely preventing the interference. An advanced position calculating section determines advanced time for the next interference check, based on an end time point of an interference check by an interference checking device and the sum of a time required for the interference check, a time required for communication, a time required for decelerating and stopping a movable part, and a predetermined float. Further, an advanced position of the movable part at the advanced time is calculated based on pre-read program data and is outputted to the interference checking device. The interference checking device performs the interference check at the advanced position. If it detects interference, the interference checking device delivers an axis stop signal to a motion command output section, thereby stopping a motion command and decelerating and stopping the movable part. Since interference check
