Abstract
Abstract An accessory for use on a numerical control (N/C) machine tool to establish the Z-axis zero setting of the spindle of the machine, including: motor driven means for rotating the manual Zaxis actuator of the machine; a manually operable switch for energizing the motor driven means; a gauge block on the Z axis and engageable by a cutting tool carried by the spindle; and a switch actuable by the gauge block, when engaged by the cutting tool, to de-energize the motor driven means. Thus, the spindle is stopped at the desired Z-axis zero setting for the particular cutting tool.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
168 words
IN AN AUTOMATIC POSITIONING ACCESSORY FOR A MOVABLE COMPONENT OF A MACHINE HAVING A DRIVE FOR SAID MOVABLE COMPONENT AND A ROTARY ACTUATOR WHICH CONTROLS SAID DRIVE AND WHICH IS NORMALLY MANUALLY OPERATED, THE COMBINATION OF: A. MOTOR DRIVE MEANS FOR ROTATING SAID ROTARY ACTOATOR; B. MANUALLY OPERABLE SWITCH MEANS FOR ENERGIZING SAID MOTOR DRIVEN MEANS; C. GAUGE MEANS ON THE AXIS OF MOVEMENT OF SAID MOVABLE COMPONENT; D. SWITCH MEANS INCORPORATED IN SAID GAUGE MEANS FOR DEENERGIZING SAID MOTOR DRIVEN MEANS UPON ARRIVAL OF SAID MOVABLE COMPONENT AT A PREDETERMINED POSITION ON SAID AXIS; E. SAID GAUGE MEANS BEING CARRIED BY A STATIONARY COMPONENT OF SAID MACHINE AND BEING ENGAGEABLE BY SAID MOVABLE COMPONENT OF SAID MACHINE TO ACTUATE SAID SWITCH MEANS; F. SAID GAUGE MEANS INCLUDING A MOVABLE GAUGE BLOCK ENGAGEABLE BY SAID MOVABLE COMPONENT OF SAID MACHINE; AND G. SAID SWITCH MEANS INCLUDING A SWITCH ENGAGING SAID GAUGE BLOCK AND ACTUABLE BY SAID GAUGE BLOCK UPON ENGAGEMENT OF SAID MOVABLE COMPONENT OF SAID MACHINE THEREWITH.
