Abstract

PURPOSE:To enable a highly accurate measurement by detecting the angle of inclination of an arm with a deviation dimension detector when a stylus abuts on a deviation dimension inspecting surface with the known deviation dimension from the reference line to confirm the accurate position of the stylus tip. CONSTITUTION:The movement of an arm support body 21 in the direction X as connected to a nut 19 is detected with an X-direction detector 18. An arm 1 having a stylus 2 mounted at the tip thereof is supported rotatably on the support body 21 and the displacement of the stylus 2 tip in the direction Y is detected with Y-direction detector 22. In addition, a deviation dimension reference body 23 having a deviation dimension inspecting surface 24 is mounted detachably, where the deviation dimension H from the reference line T is known. Then, the angle of inclination of the arm 1 when the tip of the stylus 2 abuts the inspecting surface 24 is detected with the detector 22 serving as a deviation dimension detector whereby a fine deviation DELTAH is determined from the deviation demension H. The angle of inclination of the arm 1 when the stylus 2 moves abutting on the surface of an object 26 to be measured is also detected with the detector 22. Based on these detection values, a circular arc error is corrected.

(2) When the arc error correction means 31 is mechanical, the tip of the stylus 2 is placed on the inspection surface 24 using the deflection method. Y direction detector 22 as a deviation dimension detector when brought into contact with each other
Using this as an index, the stylus 2 can be replaced, etc., and subsequent measurements can be made without error.

In addition, in carrying out the method, the Y direction detector 22 is also used as the deflection/j method detector that detects the inclination angle of A1 when the stylus 2 is brought into contact with the inspection surface 24. It is not limited to this case, and it may be provided separately from the Y direction detector 22. <H, and if this Y direction detector 22 is also used,
This is extremely convenient because the deviation in the Y direction and the deviation ΔH from the deviation\J method H, which are the original measured values, can be calculated together by simply operating the switching means 32 in the width direction.

In addition, the deflection=J method inspection body 23 is fixed to the arm support 21.
Is it okay to ask someone about this, etc.?
This has the effect that there is no risk of interfering with the measurement of the Δlit constant object 26, and that the deviation dimension H can be set to various values.
