Reseat system for touch probe in coordinates measuring machine

摘要

A reseat system capable of restraining reseat shift in returning from escape movement and thus capable of obtaining reseat return accuracy without adding separate mechanism is provided. A locus drawn by a tip of a stylus when the stylus moves parallel to an axis thereof at a rest position while a hard ball on a fixed component is in contact with a cylindrical body on a movable-component having the stylus is inclined in a direction of a biasing force. When a pressing force is applied to the movable component, since a reaction force against the pressing force is generated at a contact point of the cylindrical body and the hard ball, reseat shift of the movable component can be restrained.
