  • Publication number: 20230356346
    Abstract: A processing machine includes a drive source, a camera, an image processing device and a control device. The drive source makes a workpiece and a tool relatively move in a first direction. The camera captures the tool in the first direction to acquire an image. The image processing device identifies a position of the tool in the first direction based on clarity of the tool in the image. The control device controls the first drive source based on the position of the tool in the first direction identified by the image processing device.
