Abstract
A computer numerical control machine has a power head and a tool holder rotatable coupled to the power head. A collision sensor issues a collision signal upon detecting a collision of the tool holder with an object. The collision sensor may be in the form of thermometer measuring the temperature of the tool holder, a light sensor detecting proximity of an object to the tool holder, or a protecting sleeve mounted onto the tool holder.
Claims21
A protective sleeve mountable on a tool holder configured for holding a milling cutter, said protective sleeve having an internal portion facing said tool holder and an opposite external portion;
- said sleeve comprising:
- a. a first electrically insulating layer;
- b. a first electrically conductive layer provided concentrically with the inner portion of said first electrically insulting layer;
- c. a resilient insulating layer provided concentrically with the inner portion of said first electrically conductive layer;
- and
- d. a second electrically conductive layer, provided concentrically with the inner portion of said resilient insulating layer.
A tool holder for a computer numerical control machine, comprising:
- a. a tool holder body having exterior cylindrical surface;
- b. a sleeve mounted on the exterior cylindrical surface of the tool holder, the sleeve comprises a resilient insulation layer provided around the exterior cylindrical surface of the tool holder, and an exterior electrically conductive layer provided over and concentric with the resilient insulation layer;
- wherein the exterior electrically conductive layer is electrically-interconnected with a controller configured for stopping motion of the tool holder upon receiving a collision signal from the exterior electrically conductive layer.
A computer numerically controlled (CNC) machine, comprising:
- a. a power head mounted on a base;
- b. a tool holder rotationally mounted onto the power head;
- c. a controller;
- d. a collision sensor detecting potential collision of the tool holder with an object and issuing a collision signal to the controller indicating the potential collision of the tool holder.
