Abstract
Disclosed is a machining system wherein provisions are made to be able to remove machining chips reliably without requiring human intervention. The machining system includes: an image processing unit which detects the position and amount of machining chips by comparing images captured of a workpiece and a machining tool before and after execution of a machining step; a condition judging unit which, based on the detected amount of machining chips, determines whether or not there is a need to execute a removal step; and a result judging unit which judges the result of the removal step by comparing the images captured of the workpiece W and the machining tool before and after the execution of the removal step.
Claims15
A machining system comprising:
- a machine tool equipped with a machining tool;
- a robot configured to be able to use selectively a gripper capable of gripping a workpiece to be machined by the machine tool and a removal tool used for removing machining chips;
- and an image capturing device attached to a moving part of the robot, wherein the machining system includes:
- an image processing unit which detects position and amount of the machining chips adhering to the workpiece and the machining tool by comparing a first reference image acquired by shooting the workpiece and the machining tool with the image capturing device before starting the machining with a first target image acquired by shooting the workpiece and the machining tool with the image capturing device after starting the machining;
- a condition judging unit which determines whether or not there is a need to remove the machining chips, based on the amount of the machining chips detected by the image processing unit;
- a removal executing unit which, if it is determined by the condition judging unit that there is a need to remove the machining chips, then operates the robot and executes a removal step to remove the machining chips using the removal tool, based on the position of the machining chips detected by the image processing unit;
- and
- a result judging unit which judges a result of the removal step by comparing a second reference image acquired by shooting the workpiece and the machining tool with the image capturing device just before the execution of the removal step with a second target image acquired by shooting the workpiece and the machining tool with the image capturing device immediately after the execution of the removal step.
