Abstract
Abstract A platform is mounted for movement in x and y directions and carries a stylus, vibrator and a cutting tool. An operator moves the stylus along a master pattern causing the cutter to cut the master pattern in a sheet of suitable material, such as, 1/16 inch magnesium, plastic or alluminumate.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
247 words
Apparatus for controlled cutting comprising, stylus means for tracing a master pattern, cutting means for cutting the copy of the pattern traced by said stylus in a cutting plane parallel to the plane of said master pattern, means for mechanically intercoupling said stylus means and said cutting means so that movements of said stylus are followed by said cutting means, means for vibrating at least said stylus means in a direction orthogonal to said cutting plane, said stylus means, said cutting means and said means for mechanically intercoupling including said means for vibrating to form an assembly vibrated by said means for vibrating, base means, and means for supporting said assembly on said base for permitting slight displacement thereof in a direction orthogonal to said cutting plane, said means for supporting comprising means for allowing relative displacement of said assembly in a first direction parallel to said cutting plane and in a second direction orthogonal to said first direction parallel to said cutting plane and further comprising, at least one rod comprising the inside race of a ball-bearing and of generally elliptical cross section having a minor diameter orthogonal to said cutting plane only slightly less than its major diameter and surrounded by an outer race of circular cross section with balls therebetween, the inside diameter of said outer race in the channel thereof including said balls having a diameter substantially equal to the major diameter of said rod plus twice the diameter of a said ball.
Claim 2
Dependent Claim
247 words
Apparatus for controlled cutting comprising, stylus means for tracing a master pattern, cutting means for cutting the copy of the pattern traced by said stylus in a cutting plane parallel to the plane of said master pattern, means for mechanically intercoupling said stylus means and said cutting means so that movements of said stylus are followed by said cutting means, means for vibrating at least said stylus means in a direction orthogonal to said cutting plane, said stylus means, said cutting means and said means for mechanically intercoupling including said means for vibrating to form an assembly vibrated by said means for vibrating, base means, and means for supporting said assembly on said base for permitting slight displacement thereof in a direction orthogonal to said cutting plane, said means for supporting comprising means for allowing relative displacement of said assembly in a first direction parallel to said cutting plane and in a second direction orthogonal to said first direction parallel to said cutting plane and further comprising, at least one rod comprising the inside race of a ball-bearing and of generally elliptical cross section having a minor diameter orthogonal to said cutting plane only slightly less than its major diameter and surrounded by an outer race of circular cross section with balls therebetween, the inside diameter of said outer race in the channel thereof including said balls having a diameter substantially equal to the major diameter of said rod plus twice the diameter of a said ball.
Claim 3
Dependent Claim
35 words
Apparatus for controlled cutting in accordance with claim 1 wherein there are two mutually orthogonal pairs of said rods for allowing said stylus and cutting means to move together in said first and second directions.
Claim 4
Dependent Claim
184 words
Apparatus for controlled cutting comprising, stylus means for tracing a master pattern, cutting means for cutting the copy of the pattern traced by said stylus in a cutting plane parallel to the plane of said master pattern, frame means for mechanically intercoupling said stylus means and said cutting means in fixed relationship so that movements of said stylus are followed by said cutting means, base means, means for supporting said frame means on said base means to allow displacement of said frame means relative to said base means in first and second orthogonal directions parallel to said cutting plane, said means for supporting comprisIng at least one rod comprising the inside race of a ballbearing and of generally elliptical cross section having a minor diameter orthogonal to said cutting plane only slightly less than its major diameter and surrounded by an outer race of circular cross section with balls therebetween, the inside diameter of said outer race in the channel thereof including said balls having a diameter substantially equal to the major diameter of said rod plus twice the diameter of a said ball.
Claim 5
Dependent Claim
184 words
Apparatus for controlled cutting comprising, stylus means for tracing a master pattern, cutting means for cutting the copy of the pattern traced by said stylus in a cutting plane parallel to the plane of said master pattern, frame means for mechanically intercoupling said stylus means and said cutting means in fixed relationship so that movements of said stylus are followed by said cutting means, base means, means for supporting said frame means on said base means to allow displacement of said frame means relative to said base means in first and second orthogonal directions parallel to said cutting plane, said means for supporting comprisIng at least one rod comprising the inside race of a ballbearing and of generally elliptical cross section having a minor diameter orthogonal to said cutting plane only slightly less than its major diameter and surrounded by an outer race of circular cross section with balls therebetween, the inside diameter of said outer race in the channel thereof including said balls having a diameter substantially equal to the major diameter of said rod plus twice the diameter of a said ball.
Claim 6
Dependent Claim
