Three-dimensional cutting tool

Abstract

A tool and method for cutting an object three dimensionally is disclosed having a lower receiving plate comprising a cavity that is shaped and sized to fit a shoe last for placing a shoe sole on that is to be fully or partially cut, and an upper pressing plate comprising a segmented sub-plate comprising individually spring-backed segments, further comprising a cutting blade substantially surrounding each segment.

1 . A tool for cutting an object three dimensionally, comprising:
 a lower receiving plate comprising a cavity that is shaped and sized to fit a shoe last for placing a shoe sole on that is to be fully or partially cut;   an upper pressing plate comprising a segmented sub-plate comprising individually spring-backed segments; and   a cutting blade substantially surrounding each segment.   
     
     
         2 . The tool of  claim 1 , wherein the shoe sole that is to be cut is bottom of an outsole, wherein the bottom of the outsole faces the cutting blade. 
     
     
         3 . The tool of  claim 1 , wherein the lower and upper plate is made of aluminum or steel. 
     
     
         4 . The tool of  claim 1 , wherein the shoe last is made of metal, aluminum or hard plastic or rubber. 
     
     
         5 . The tool of  claim 1 , wherein the lower plate comprises a height adjuster in the cavity. 
     
     
         6 . The tool of  claim 5 , wherein the height adjuster is a washer on a bolt that fits in a groove in the shoe last. 
     
     
         7 . The tool of  claim 1 , wherein the shoe last comprises a height adjuster. 
     
     
         8 . A method of cutting an object three dimensionally comprising:
 providing a lower receiving plate comprising a cavity that is shaped and sized to fit a shoe last so as to place a shoe sole that is to be fully or partially cut on the shoe last;   providing an upper pressing plate comprising a segmented sub-plate comprising individually spring-backed segments, further comprising a cutting blade substantially surrounding each segment;   placing a shoe last in the cavity of the lower receiving plate;   placing a shoe sole on the shoe last;   placing the upper pressing plate on top of the lower receiving plate;   aligning the upper and lower plates;   pressing the upper pressing plate on to the lower receiving plate, thus resulting in cut sole.   
     
     
         9 . The method of  claim 8 , wherein the lower receiving plate and upper pressing plate are loaded on to a booster press. 
     
     
         10 . The method of  claim 8 , wherein the shoe sole that is to be cut is bottom of an outsole, wherein the bottom of the outsole faces the cutting blade. 
     
     
         11 . The method of  claim 8 , wherein the lower and upper plate is made of aluminum or steel. 
     
     
         12 . The method of  claim 8 , wherein the shoe last is made of metal, aluminum or hard plastic or rubber. 
     
     
         13 . The method of  claim 8 , wherein the lower plate comprises a height adjuster in cavity. 
     
     
         14 . The method of  claim 13 , wherein the height adjuster is a washer on a bolt that fits in a groove in the shoe last. 
     
     
         15 . The method of  claim 8 , wherein the shoe last comprises a height adjuster. 
     
     
         16 . The method of  claim 8 , wherein a buffer material is placed on the shoe last before placing on the shoe sole.
