Abstract

Abstract There is disclosed a method of and apparatus for developing on tape and applying a preselected rotary die design, etc., defined by spaced drilled holes, to a rotary die board automatically by a tape controlled apparatus. A computer is programmed to produce information which is transferred to a tape, or the like, fed to a numerical control machine to energize selected mechanisms to physically apply a preselected design formed by spaced drilled holes, routing, etc., to a rotary die board for reception of the spaced tangs or legs of cutting rule, or the like, or other workings. Included in the computer programming is a foreshortening of dimensions, as required, to compensate for the relative position of the cutting rule edge. Illustrated is an apparatus for drilling or drilling and routing rotary die board including an electrically actuatable structure for rotatably supporting rotary die board, an electrically actuatable traversable supporting structure for a drill head, and an electrically actuatable drill head adapted to execute desired reciprocable movements and to drill spaced holes and to rout, as signaled.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 125 words
In combination, a system for providing a preselected design and accurately applying it to die board for the drilling of spaced holes therein adopted to receive the tangs or legs of cutting rule comprising means for developing data for a preselected die design adapted to be converted to a punched tape and the like, means for converting said developed data into a punched tape and the like, mechanism for receiving said tape responsive thereto to produce electrical impulses, and means responsive to said electrical impulses adapted to physically apply said preselected design to a die board in the form of spaced holes, said spaced holes embodying said physically applied preselected design being adapted to receive the spaced tangs or legs of cutting rule so formed.
Claim 2
Dependent Claim 125 words
In combination, a system for providing a preselected design and accurately applying it to die board for the drilling of spaced holes therein adopted to receive the tangs or legs of cutting rule comprising means for developing data for a preselected die design adapted to be converted to a punched tape and the like, means for converting said developed data into a punched tape and the like, mechanism for receiving said tape responsive thereto to produce electrical impulses, and means responsive to said electrical impulses adapted to physically apply said preselected design to a die board in the form of spaced holes, said spaced holes embodying said physically applied preselected design being adapted to receive the spaced tangs or legs of cutting rule so formed.
Claim 3
Dependent Claim 13 words
The combination of claim 1 in which the die board worked is arcuate.
Claim 4
Dependent Claim 19 words
The combination of claim 2 in which said first means comprises a computer programmed to foreshorten dimensions not axial.
Claim 5
Dependent Claim 24 words
The combination of claim 3 in which said mechanism comprises a tape controlled unit programmed to control a selected number of electrically actuated machines.
Claim 6
Dependent Claim 38 words
The combination of claim 2 in which said means responsive to said electrical impulses comprises a plurality of electrically actuated machines adapted to support a rotary die board and selected tools for physically working the rotary die board.
Claim 7
Dependent Claim 31 words
The combination of claim 5 in which said electrically actuated machines are adapted to repeat the preselected design with high accuracy on a single die board and on successive die board.
Claim 8
Dependent Claim 25 words
The combination of claim 6 and including an electrically actuated drill adapted to drill spaced holes in a rotary die board defining the preselected design.
Claim 9
Dependent Claim 19 words

Claim 10
Dependent Claim 33 words
The combination of claim 8 in which a rotary die board is rotatively supported and said drill is supported for traversing movement to provide combined universal positioning of said drill and routing means.
Claim 11
Dependent Claim 18 words
The combination of claim 9 in which the developed data includes foreshortening of dimensions not on axial lines.
