IPC: G01B21/20
Filed: 1988-10-01
Abstract: PURPOSE:To measure the shape and the size of a minute V-shaped groove at a high accuracy of 1.0mum or less by moving the stylus of a contact-type shape measuring device vertically with respect to the longitudinal direction of the V-shaped groove, and measuring 20 or more points per V-shaped groove on the surface. CONSTITUTION:A stylus 3 of a contact-type shape measuring device is moved in the direction perpendicular to the longitudinal direction of a V-shaped groove 1 on a surface 4 where the V-shaped grooves 1 are machined. The coordinates of 20 or more points per V-shaped groove 1 on the surface are measured. The dimensions of the V-shaped groove 1 are as follows: width W is about 150mum; depth M is about 100mum; pitch L is about 250mum; and opening angle theta is 70 deg. or more. As the stylus 3, a stylus having a tip angle of 60 deg. and a tip R of 2mum can be used. Since the measured data of an edge part 5 and a groove bottom part 6 of the V-shaped groove 1 are unstable, the length of 10mum or more is removed for each part. The shape that is formed with straight lines is computed by a computing method such as a least square method based only the measured data for the remaining part whose effective measuring length is 40mum or more.
