Abstract

A method of displaying an image on a work piece positioned on a movable work surface. A method of processing a work piece, as well as a method of displaying an image on a moveable work surface, is also provided. A system for machining a work piece in accordance with one or more images projected onto the work piece is also provided.

Claims (24)

1. A method of displaying an image on a work piece positioned on a movable work surface, comprising:

(a) providing a digital representation of an image and a laser projection system configured to project said image based on said digital representation;

(b) providing a work piece positioned on a movable work surface;

(c) projecting said image from said laser projection system onto said work piece at a selected image location on the work piece;

(d) moving said work surface, with said work piece supported by said work surface;

(e) sensing the movement of said work surface and transmitting to said laser projection system a feedback signal indicative of said movement; and

(f) moving said projected image in response to said feedback signal such that said image is projected on the work piece at said selected image location.

2. A method of processing a work piece, comprising the steps of:

(a) projecting an image onto a work piece to be processed;

(b) moving at least one of said image and said work piece until said image is positioned at a desired location on said work piece;

(c) locking said image and said work piece such that, as said work piece is moved, said image will remain at said desired location; and

(d) processing said work piece using said image as a guide.

3. A method of displaying an image on a moveable work surface, comprising:

(a) providing a digital representation of an image and a laser projection system configured to project said image based on said digital representation;

(b) providing a movable work surface;

(c) projecting said image from said laser projection system onto said work surface at a selected image location on the work surface;

(d) moving said work surface;

(e) sensing the movement of said work surface and transmitting to said laser projection system a feedback signal indicative of said movement; and

(f) moving said projected image in response to said feedback signal such that said image is projected on the work surface at said selected image location.

4. A system for machining a work piece in accordance with at least one image projected onto the work piece, comprising:

(a) a processing machine having a moveable work surface configured for supporting a work piece thereon, said processing machine configured for machining a work piece supported on said work surface;

(b) an optical projection system for projecting at least one image onto a work piece supported by said work surface, said optical projection system including an optical projector and a control system;

(c) at least one sensor for sensing movement of said work surface, wherein said at least one sensor is configured to provide a signal to said control system indicative of movement of said work surface;

wherein said optical projection system is configured such that an image projected onto a work piece will be projected in the same location on the work piece when said work surface is moved.
