Operation simulation system of robot system

An operation simulation system for simulating, on a computer, operation of a robot system having a robot, a machine tool and a peripheral device, the robot system including moving members configured to move in accordance with a predetermined operating program, the operation simulation system comprising:

• a memory storing in advance the operating program, shape data of the moving members, and shape data of a workpiece;
• a setting unit configured to set movement points, which are configured to move together with the moving members, at specific portions of the robot and the machine tool or at specific portions of the robot and the peripheral device which are linked with the moving members,
• wherein the movement points are set based on different positional coordinates of the corresponding moving members;
• a data acquisition unit configured to acquire time series position data of the movement points when simulating operation of the robot system in accordance with the operating program on the computer;
• an image generation unit configured to generate
• an image of the robot system operating in accordance with the operating program based on (i) the simulated operation of the robot system on the computer and (ii) the shape data of the moving members and the shape data of the workpiece stored in the memory, and
• an image of movement paths of the corresponding movement points based on the time series position data acquired by the data acquisition unit;
• and
• a display unit configured to display the image of the robot system and the image of the movement paths generated by the image generation unit.
