Title:
METHOD AND DEVICE FOR MANUFACTURING PRODUCT BY UTILIZING HOLOGRAPHY TECHNIQUE
Document Type and Number:
WIPO Patent Application WO/1982/003798
Kind Code:
A1
Abstract:
Method of directly manufacturing a product using holographic techniques to geometrize information, and a machine tool according to the same method. A conventional machine tool manufactures a desired product by cutting a mineral material solidified in the prescribed shape with a cutting edge, a laser or the like, and is an external machining method. Accordingly, it is limited by its design from directly manufacturing a complicated or topological product such as something with an internal structure. This invention overcomes this disadvantage. By the application of a holographic technique capable of arbitrarily performing a spatial distribution of electromagnetic or sonic wave as the wave energy, the design information of the product obtained in advance can be obtained as a spatial energy distribution, the design information of the three dimensional product is solidified through the sublimation of gasified material utilizing the difference between the high and the low wave energies in the spatial distribution, e.g., the temperature difference, thereby directly manufacturing the product.
