CUTTING PROCESS AND CUTTING DEVICE
First Claim
1. A process for cutting a work piece by irradiating first and second irradiation regions on a front surface of the work piece with first heating light and second heating light and relatively moving the first and second irradiation regions along a planned cutting line on the front surface;
- wherein a width of the first irradiation region extending in a direction orthogonal to the moving direction thereof is smaller than a width of the second irradiation region extending in a direction orthogonal to the moving direction thereof, and the first irradiation region is moved in tandem with the second irradiation region preceding the first irradiation region.

Abstract
In a process for cutting a work piece 10 by irradiating a front surface 11 of the work piece 10 with first heating light 43 and second heating light 44 and moving the irradiation regions 100 and 200 of each light along a planned cutting line 12 on the front surface 11, the first heating light 43 has a width W1 extending in a direction orthogonal to the moving direction thereof on a certain area of the front surface 11, the width of the first heating light being set so as to be smaller than a width W2 of the second heating light 44 extending in a direction orthogonal to the moving direction of the second heating light, and the irradiation region 100 of the first heating light 43 being moved in tandem with the irradiation region 200 of the second heating light 44, which precedes the first irradiation region.

14. A system for cutting a work piece, comprising a stage for supporting a work piece;
- sources for first heating light and second heating light, with which a front surface of the work piece is irradiated; and
a controller, the controller controlling respective first and second irradiation positions of the first and second heating light on the front surface, and the controller moving the first and second irradiation regions along a planned cutting line on the front surface relatively with respect to the work piece such that the work piece is cut;wherein the cutting system further comprises an irradiation device and the controller for the first and second irradiation regions, the irradiation device irradiating the first heating light and the second heating light such that a width of the first irradiation region extending in a direction orthogonal to the moving direction of the first irradiation region is smaller than a width of the second irradiation region extending in a direction orthogonal to the moving direction of the second irradiation region, and the controller for the first and second irradiation regions moving the first irradiation region in tandem with the second irradiation region preceding the first irradiation region. - View Dependent Claims (15)
