Abstract

[Problem] The purpose of the present invention is to provide a laser slicing method that makes a cutting cross-section on a wafer smooth, reduces a cutting load, and is effective for the improvement of a material yield. [Solution] The laser slicing method is used for cutting and manufacturing a wafer by performing movement scanning with laser light relative to a base material while forming a light-focused point at a prescribed depth from the base material surface having a prescribed off-angle between the central axis and the crystal orientation (C-axis) of the base material, thereby forming a modified layer and a crack, the method being characterized in that, in the scanning direction in which the movement scanning is performed, dot irradiation is performed linearly in the inclination direction of a crystal plane orthogonal to the C-axis.

Abstract

A collision stress releasing device reversely rotates a feed motor by a return amount set in a return amount setter based on a contact position of a movement unit or a collision detection position regarded as a contact position. Generally, a large error does not occur even when the collision detection position is regarded as the contact position, but when the movement unit or the colliding member has low rigidity, a control of setting a return amount in response to the speed of the movement unit or a control of estimating an actual contact position from a rise curve of a load after a collision is more desirable.

Abstract

A method and a device can measure machine error of an axis of rotation in a tool post having a touch probe without restriction of an angular range of an angle of rotation. Directions of a measurement plane and a measurement axis in a five-axis measurement are switched in correspondence to a range of the angle of rotation in a touch probe. The five-axis measurement is carried out by setting a position in a direction of a measurement axis in a measurement plane to a position where a reference sphere does not interfere with a lever rod of the touch probe as occasion demands. The five-axis measurement is carried out, for example, by setting the measurement plane to a position which is perpendicular to a line connecting an estimated center of the reference sphere and a center of a tip sphere or the lever rod of the touch probe.
