Definitions

  • the present invention relates to a method and apparatus for manufacturing 3- dimensional shaped products using a machining process.
  • Rapid manufacturing of a 3-dimensional shaped product refers to the rapid manufacture of a 3-dimensional shaped prototype product, using the same material as that of the actual product.
  • a product manufactured according to this process is called a rapidly manufactured product, in which a prototype, a mock-up, or the like manufactured before its mass-production is primarily included. If the product to be mass-produced requires a complex geometrical shape and a high degree of precision, the rapidly manufactured product as the prototype should have the complex geometrical shape, and the degree of precision thereof should also be very stringent.
  • RP Rapid Prototyping
  • This method is largely classified into two types: a method of curing liquid photo-sensitive material by irradiating a laser beam thereon to manufacture a 3-dimensional shaped product; and a method of forming a desired shape by bonding granular or layer solid material.
  • the rapid manufacturing process refers to a process of manufacturing a 3-dimensional shaped prototype or mold directly from 3-dimensional CAD data using various nonmetallic material such as paper, wax, ABS and plastic, or metallic material.
  • various processes using metal powder and metal wires as the material have been developed.
  • SLA Stereolithography
  • This method includes two types: locally irradiating a laser beam (for example, this type is performed in 3D system, Inc., Quadrax corporation, Sony, Inc., Du pont, Inc., etc.); and irradiating a laser beam one layer at a time using an ultraviolet lamp (for example, this type is performed in Cubital,
  • a method of manufacturing a desired shape using powder material includes a Selective Laser Sintering (SLS) method used in DTM Corp., etc. and a 3-dimensional printing (3DP) method used in Solingen, GmbH, Z, Corp., etc. and developed by MIT.
  • SLS Selective Laser Sintering
  • 3DP 3-dimensional printing
  • a product is manufactured in a manner of coating powder material of plastic resin and then binding the powder material by irradiating a laser beam.
  • a metal part or mold may be manufactured by using iron powder which is coated with plastic resin.
  • a post- process such as sintering or Cu infiltration is required. Since a contraction phenomenon due to heat deformation may be generated during the post-process, it is difficult to obtain a desired degree of dimensional precision.
  • a product is manufactured in a manner of selectively sprinkling liquid binder over coated powder.
  • a ceramic shell for investment casting can be manufactured directly from ceramic powder, or a part can be manufactured by using starch based powder material. During this process, since a post-process is essential to increase the density and strength of the product, a contraction phenomenon due to heat deformation may be generated.
  • a product is manufactured by repeating a process of bonding a sheet of thin paper by using a heated roller and then cutting a predetermined portion of the paper with a laser beam.
  • LOM Laminated Object Manufacturing
  • a part is manufactured in a manner of melting plastic resin material in the form of a filament by passing the material between heated nozzles having a shape similar to that of an extruding metal mold and then attaching the material.
  • FDM Fused Deposition Manufacturing
  • a metal deposition process is combined with a CNC machining process.
  • metal is deposited to form a layer.
  • a portion of the layer is machined to have a desired thickness and boundary shape using multi-axis CNC machining, while the remaining portion of the layer is filled with different metal material.
  • the layer is machined again by the CNC machining to complete one layer.
  • a shot peening process is performed to remove any residual stress.
  • an object of the present invention is to provide a method and apparatus for rapidly manufacturing 3-dimensional shaped products, wherein prototypes can be manufactured or job shop type production can be made.

  • the workpiece set-up unit mounted on the feed table includes a rotation shaft portion engaged with the feed table and a workpiece-securing portion for holding the workpiece.
  • a tool may approach and machine only an arbitrary side surface such as a surface of a metal mold. Accordingly, a 3-dimensional shaped prototype could not be perfectly machined. Therefore, in order to overcome such a limitation, according to the present invention, after one side surface of the workpiece is machined by allowing the tool to approach it, the machined side surface is filled with filler (for example, phase-changeable filler). Then, another side surface is repeatedly machined by using binding force of the filler. By repeating such procedures and then removing the filler, a complex and complete 3-dimensional shaped prototype can be machined with a high degree of precision in a short period of time.
