Stitch machining method by industrial robot

A stitch machining method for intermittently machining a workpiece along traveling path of an end effector attached to an industrial robot by controlling the end effector with a robot controller, said method comprising:

• setting a machining distance and a non-machining distance for the intermittent machining with a cycle of machining and non-machining, to said robot controller;
• adjusting the set machining distance and the set non-machining distance so that start and end points of a block of a motion command in an operation program coincides with start end points of said machining, respectively;
• and
• alternately performing the machining of the machining distance adjusted in said adjusting and the non-machining of the non-machining distance adjusted in said adjusting in accordance with a travel distance of the end effector from a beginning of the stitch machining.

A stitch machining method intermittently machining a workpiece along a traveling path of an end effector attached to an industrial robot by controlling the end effector with a robot controller, said method comprising:

• setting a machining distance and a non-machining distance for the intermittent machining with a cycle of machining and non-machining and also the number of cycles of the intermittent machining, to said robot controller;
• adjusting the machining distance and the non-machining distance set in said setting a machining distance so that movement in each block of an operation program taught to the industrial robot is completed with the set number of cycles of the machining and the non-machining;
• and
• alternately performing the machining of the machining distance adjusted in said adjusting and the non-machining of the non-machining distance adjusted in said adjusting in accordance with a travel distance of the end effector from a beginning of the stitch machining.

A stitch machining method intermittently machining a workpiece along a traveling path of an end effector attached to an industrial robot by controlling the end effector attached to an industrial robot by controlling the end effector with a robot controller, said method comprising:

• setting a ratio of a machining distance to a non-machining distance and the number of cycles of machining and non-machining, to said robot controller:
• (b) adjusting said ratio to obtain the machining distance and the non-machining distance so that movement in each block of an operation program taught to the industrial robot is completed with the number of cycles of machining and non-machining set in said setting;
• and
• alternately performing the machining of the machining distance obtained in said adjusting and the non-machining of the non-machining distance obtained in said adjusting in accordance with a traveling distance of the end effector from a beginning of the stitch machining.
