Workpiece's e.g. stainless steel body, surface and three dimensional shape measuring device, has probe with head that is connected with holder by inserting into head whose diameter is greater than thickness of holder at insertion into head

摘要

The device (1) has a measuring probe (9) movable relative to a workpiece holder (4). An evaluation circuit (18) is connected with measuring probe and reference electrode bodies (12, 2) over respective measuring lines (14, 7). A direct current voltage source (8) is connected with the lines, and the circuit is designed such that it measures tunnel current between the bodies. The probe has a ball shaped measuring head that is connected with a measuring head holder (13) by inserting into the head, where a diameter of the head is greater than thickness of the holder at the insertion into the head. An independent claim is also included for a method for measuring a workpiece.
