Abstract
Official abstract text for this publication.
The occurrence of grinding unevenness is prevented even when the movement speed of a robot is changed. Provided is a grinding robot system including: a motor-driven grinder that performs grinding; a robot that grinds a grinding target by means of the grinder in a state in which one of the grinder or the grinding target is attached to a distal end thereof and is moved, and the other is set at a fixed position; and a control unit that controls the robot and the grinder, wherein the control unit calculates a rotational-speed command value for the grinder that changes according to the movement speed of the distal end of the robot and controls the rotational speed of the grinder on the basis of the calculated rotational-speed command value.
First claim
Opening claim text (preview).
The invention claimed is: 1. A grinding robot system comprising: a motor-driven grinder that performs grinding; a robot that grinds a grinding target by the grinder in a state in which one of the grinder or the grinding target is attached to a distal end of the robot and is moved, and another one of the grinder of the grinding target is set at a fixed position; and a control unit that controls the robot and the grinder, wherein the control unit is provided with a storage unit that stores a plurality of functions showing the relationship between movement speed of the distal end of the robot and rotational-speed command value for the grinder, and when an operation program of the robot is executed, the control unit reads the function from the storage unit on the basis of the movement speed of the distal end of the robot instructed in the operation program of the robot, calculates a rotational-speed command value for the grinder by using the read function, and controls the rotational speed of the grinder on the basis of the calculated rotational-speed command value. 2. A grinding robot system according to claim 1 , further comprising a rotation-speed detecting unit that detects the rotation speed of the grinder or the rotation speed of a motor of the grinder, wherein the control unit feeds back the rotation speed detected by the rotation-speed detecting unit to control the rotational speed of the grinder.
