Document Type and Number:
Japanese Patent JP2019150899
Kind Code:
A
Abstract:
To prevent each strip-like piece of a plate-like material from falling during cutting processing even if the material is a composite material including a soft layer.SOLUTION: In a processing method for forming strip-like work-pieces (W) from an excess-size plate-like material (10) having a product region (12): the excess-size plate-like material having an excess region (14) at an outer periphery of the product region is made to adhere to a holding member (19); then a middle of the holding member of a one-side excess region is cut into with a cutting blade (20) from above the excess-size plate-like material so that the product region is cut along a scheduled division line (16) in a first direction; the cutting blade (20) is moved up in the other-side excess region so that the product region is cut along the scheduled division line in the first direction while leaving uncut parts (25 and 27) in the one-side and the other-side excess regions; and then the excess region in a second direction perpendicular to the first direction is cut off and removed, so as to be divided into work-pieces to be formed into strip-like pieces respectively.SELECTED DRAWING: Figure 6
