Method of manufacturing a pressure intensifying tool and tool produced thereby
First Claim
1. A method of manufacturing a tool used to direct pressure applied to areas of a plastic laminate part during co-curing or co-bonding, comprising the steps of:
- (A) generating a digital data file representing a three dimensional model of the tool; and
,(B) using the digital data file to direct automated manufacturing of the tool in which additive layers of material are successively formed until the features of the tool correspond to the three dimensional model, wherein the three dimensional model includes separate complementary pieces each having a surface for engaging and intensifying the pressure applied to the part, and wherein the three dimensional model includes at least one relief, the at least one relief comprising an elongated slot provided in the tool.

Abstract
A tool used to direct the pressure applied to features of a plastic laminate part layup during co-curing or co-bonding is manufactured using direct digital manufacturing techniques. A CAD drawing representing the tool is generated and converted into digital data file suitable for controlling the operation of a rapid prototyping machine. The tool is formed in the rapid prototyping machine by additive layering of material until the features and dimensions of the layered material correspond to the CAD drawing. The resulting tool exhibits geometries and dimensions virtually identical to the theoretical dimensions of the CAD model of the tool.

9. A tool used to direct the pressure applied to features of a plastic laminate part during co-curing or co-bonding of the part, manufactured by:
-
(A) generating a CAD drawing representing the tool and wherein the tool comprises a relief for allowing the tool to flex during the co-curing or co-bonding, wherein the relief comprises an elongated slot provided in the tool; (B) producing a digital data file corresponding to the CAD drawing; and
,(C) using the digital data file to control the operation of a rapid prototype manufacturing machine, wherein the tool is formed by additive layering of material in the machine until the features and dimensions of the layered material correspond to the CAD drawing. - View Dependent Claims (10, 11, 12)
