Abstract
A bench mounted machine allows an operator to produce both mating components for woodworking through and half-blind dovetails in workpieces suitable for case construction and drawer construction with computer controlled programmable flexibility to determine size and centerline spacing of pins and tails as well as half-pin widths. Symmetrical and asymmetrical through and half-blind dovetail configurations can be created without the use of guide templates or fixed spindle arrangements. Stationary workpieces are mounted vertically and horizontally above an automated two axis dovetail cutting means. Pins and tails for interlocking through and half-blind dovetail joints are milled in the ends of workpiece boards based upon operator input commands from a personal computer control station.
Claims11
A method of cutting both mating components for woodworking half-blind dovetail joints comprising the steps of:
- programming a personal computer control station;
- mounting a first workpiece board vertically and a second workpiece board horizontally;
- positioning adjustable locking stops on vertical and horizontal clamping surfaces;
- clamping the vertically and horizontally mounted first and second workpiece boards;
- inserting a dovetail shaped bit into the collet of a router cutting means and adjusting its height;
- initiating a computer program from a personal computer control station that will direct the movements of a router cutting means first to the vertically mounted first workpiece to mill the tails of the joint, then to the horizontally mounted second workpiece to mill the pins of the joint, and return it to its home position.
A method of cutting both mating components for woodworking through dovetail joints comprising the steps of:
- programming a personal computer control station;
- mounting a first workpiece board vertically;
- positioning adjustable locking stops on a vertical clamping surface;
- clamping the vertically mounted first workpiece board;
- inserting a dovetail shaped bit into the collet of a router cutting means and adjusting its height;
- initiating a computer program from a personal computer control station that will direct the movements of a router cutting means to the vertically mounted workpiece to mill the tails of the joint, and then return it to its home position;
- removing the finished first workpiece board from within the vertical clamping means;
- mounting a second workpiece board within the vertical clamping means;
- positioning adjustable locking stops on a vertical clamping surface;
- clamping the vertically mounted second workpiece board;
- inserting a straight cutter into the collet of a router cutting means and adjusting its height;
- initiating a computer program from a personal computer control station that will direct the movements of a router cutting means to the vertically mounted second workpiece to mill the pins of the joint, and then return it to its home position.
A computer controlled machine for cutting both mating components for woodworking through and half-blind dovetail joints in workpieces suitable for case construction and drawer construction comprising:
- vertical and horizontal clamping means supported by a housing and mounted upon a base plate;
- a position table capable of x and y axis linear motion mounted upon the base plate and free to move beneath the clamping means;
- a router cutting means mounted upon the x-y position table;
- and
- adjustable locking stops to accurately position vertically and horizontally mounted workpiece boards for production run setups.
