A machining system having a function for restricting operations of a robot and a machine tool

摘要

A processing system (1) having a machine tool (20) controlled by a numerical controller (40) and a robot (10) performing operations controlled by a robot controller (30), the processing system (1) Comprising: an operator detecting device (50) that detects whether or not an operator is present in an area in which the operator is exposed to danger in the processing system, the robot (10) having an operation determining part that restricts operation of the machine tool ( 20) based on a detection result obtained by the operator detection device (50), and a notification part that notifies the numerical controller (40) of an operation restriction determined by the operation determination part, and wherein the numerical controller (40) is configured to operate the machine tool (20) according to the operating restriction, the durc h is notified to the notification part, the operation determination part having at least two operation restriction levels, a memory storing contents and settings of operation restrictions corresponding to the operation restriction levels, and setting the operation restrictions stored in the memory by selecting the operation restriction level wherein the operating restrictions include a limitation on the opening and closing speed of a door of the machine tool (20), a table feed speed and a spindle rotation speed.
