Abstract
Abstract Apparatus for selectively machining interfitting parts such as tools and moulds wherein the apparatus permits the parts to be preliminarily interfitted, and selectively positions the parts for either mechanical machining or spark-erosion machining. After preliminary interfitting movable support means for the parts is selectively positioned as determined by the type of machining to occur. The apparatus includes spark-erosion equipment directly permitting the parts to be spark-erosion machined after preliminary fitting, and dual support means translating apparatus is employed to support the upper fitted part.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
186 words
Apparatus for selectively machining first and second interfitting parts by mechanical means and spark-erosion means comprising, in combination, a supporting frame, first support means for said first part, means movably mounting said first support means upon said frame for transfer of said first support means between a first mechanical machining means access position and a second spark-erosion machining position, second support means for said second part, meaNs movably mounting said second support means on said frame for transfer of said second support means toward and away from said first support means when in said second position, and movable between a first mechanical machining means access position and a second spark-erosion machining position, said first and second support means being aligned with each other when in said second position, motor means mounted on said frame operatively connected to said first and second support means for transferring said first and second support means upon their associated movable mounting means, and spark-erosion means electrically connectable to said parts whereby said parts may be machined by spark-erosion when said first and second support means are in said second machining positions.
Claim 2
Dependent Claim
186 words
Apparatus for selectively machining first and second interfitting parts by mechanical means and spark-erosion means comprising, in combination, a supporting frame, first support means for said first part, means movably mounting said first support means upon said frame for transfer of said first support means between a first mechanical machining means access position and a second spark-erosion machining position, second support means for said second part, meaNs movably mounting said second support means on said frame for transfer of said second support means toward and away from said first support means when in said second position, and movable between a first mechanical machining means access position and a second spark-erosion machining position, said first and second support means being aligned with each other when in said second position, motor means mounted on said frame operatively connected to said first and second support means for transferring said first and second support means upon their associated movable mounting means, and spark-erosion means electrically connectable to said parts whereby said parts may be machined by spark-erosion when said first and second support means are in said second machining positions.
Claim 3
Dependent Claim
64 words
Apparatus for selectively machining first and second interfitting parts as in claim 1 wherein said first support means comprises a table mounted upon guides for positioning said table between said first and second first support means positions, and guide means mounted upon said frame transversely disposed to said guides permitting movement of said table when at said second position toward said second support means.
Claim 4
Dependent Claim
34 words
Apparatus for selectively machining first and second interfitting parts as in claim 1, first part fastening means mounted upon said second support means selectively releaseably connecting said second part with said second support means.
Claim 5
Dependent Claim
33 words
Apparatus for selectively machining first and second interfitting parts as in claim 3, second releaseable fastening means mounted on said second support means selectively fastening said second part to said second support means.
Claim 6
Dependent Claim
37 words
Apparatus for selectively machining first and second interfitting parts as in claim 1, pivot means mounted on said frame pivotally supporting said second support means on said frame for positioning between said first and second positions thereof.
Claim 7
Dependent Claim
52 words
Apparatus for selectively machining first and second interfitting parts as in claim 1, spark-erosion part translating means mounted upon said frame selectively connectable to an interfitted part for translating said part toward said first support means when in said second position to accurately translate said part to be interfitted during spark-erosion machining.
Claim 8
Dependent Claim
31 words
Apparatus for selectively machining first and second interfitting parts as in claim 1, a liquid receiving trough defined on said first support means for receiving a dielectric fluid during spark-erosion machining.
