摘要: An offset amount calibrating method that obtains the offset amount between a contact-type detector and an image probe for a surface profile measuring machine is provided. The method includes: setting on a stage a calibration jig that has a surface being provided with a lattice pattern with a level difference; measuring the lattice pattern of the calibration jig by the contact-type detector to obtain a first reference position of the lattice pattern; capturing the image of the lattice pattern of the calibration jig by the image probe to obtain a second reference position of the lattice pattern; and obtaining the offset amount from a difference between the first and second reference positions.

摘要: A surface texture measuring machine includes: a stage, a contact-type detector having a stylus, an image probe, a relative movement mechanism and a controller. The controller includes: a center position calculating unit that, when the image probe enters position data of at least three points on a circular contour of a circular concave portion or a circular convex portion of an object, approximates the entered position data to a circle to obtain a center position of the circle; and a stylus setting unit that, after calculating the center position, operates the relative movement mechanism to position the stylus of the contact-type detector at the center position.
