Abstract
A tooling device for numerically controlled machining centers having programmable torque, thrust and surface sensing utilizing a telescopic tool holder comprising an adapter to be retained in the taper of the machine spindle and a control rod in the spindle attached to an actuating rod having electronic coupling means to control the axis feed rate of the computer numerical control for controlling deceleration of the spindle and a transducer for producing a signal to feed the spindle to a programmable depth and to measure the tool thrust and torque and to sense the location of work surfaces with random length tools and also be able to control feed rate of tool proportional to tool thrust or torque.
