Abstract
A mechanism for providing computerized control of both a rip and a crosscut fence for a table saw is disclosed. The device is adapted to utilize the output of an optimization program to accurately and economically permit the user to cut sheet stock. A personal computer is utilized to determine an optimum cutting pattern in a preselected series of patterns for a preselected inventory of finished pieces. The computer arranges the finished pieces on the inventory of sheets and displays graphically the intended output to the user. The user selects the cuts in the provided sequence and the personal computer through the use of mechanical interfaces accurately positions the fences of the table saw for each successive cut. The mechanism may also allow manual entry of selected cuts by the user.
Claims28
A power saw of the type having a tabletop cutting surface, a cutting blade mounted thereon, the power saw comprising:
- (a) at least one motor driven fence adjustably mounted to sequentially position workpiece with respect to the cutting blade;
- (b) controller means connected to said motor driven fence for controlling and indexing the movement thereof;
- (c) data input means for receiving cutting instructions from a user;
- (d) processor and memory means connected to said controller means and said data input means for compiling an optimum cut sequence and cut pattern for said workpiece from said instructions, and sequentially positioning said motor driven fence according to said optimum cut sequence as prompted by said user through said data input means;
- and
- (e) display means connected to said processor and memory means for displaying said optimum cut sequence and cut pattern in a graphic format.
