ZERO FORCE TOUCH PROBE

摘要

- 14 - Case 4329 A co-ordinate measuring system for determining the relative measurements of an object is disclosed. The system utilizes a probe which has a plurality of faces which are interconnected so as to form two parallel "X" co-ordinate probe surfaces (12) and two parallel "Y" co-ordinate probe surfaces (14). At the instant the probe contacts a surface on the object being measured, an electrical circuit is completed through the probe to ground potential via the object, causing the measurement to be displayed on a visual display device (20 or 22). In this manner, measurements along the "X" and "Y" coordinates can be made and recorded at the instant the probe contacts the respective surfaces. An automatic unlatching feature is provided wherein the probe must be a predetermined distance from both the "X" and "Y" surfaces before the system automatically resets.
