  • Publication number: 20210114349
    Abstract: Disclosed are a method for producing a laminate including a step of laminating a resin impregnated fiber reinforced composition layer on a metal member, wherein the method includes a step of forming a resin coating on the metal member and a step of laminating a resin impregnated fiber reinforced composition layer containing a resin impregnated fiber reinforced composition containing (I) 20 to 80% by mass of a polymer having a melting point and/or a glass transition temperature of 50 to 300° C., and (C) 20 to 80% by mass of a reinforcing fiber (provided that the sum of the component (I) and the component (C) is taken as 100% by mass) via the above resin coating; and a laminate obtained by the method.

  • Patent number: 5317519
    Abstract: In a machining simulation system, reading from a shape memory in place of a graphic memory is effected synchronizing with scanning of a display device because of a material shape being held in the shape memory. The step of graphic memory depiction can be omitted by a cross-section display circuit for generating video signals. The animation picture can be speeded up regardless of a processing capability of a CPU. Further, data structures of the material and tool shapes are relatively simple. Hence, a change of the material shape can be speeded up irrespective of the CPU processing capability due to a shape change circuit for effecting a comparative arithmetic operation by directly reading the material shape from the shape memory and the tool shape from the pattern memory.

  • Patent number: 5255201
    Abstract: A numerical control information generating apparatus has a function of automatically correcting machining conditions by calculating corrected machining conditions from corrected numerical control information. The apparatus also has a valid/invalid setting function of automatically correcting machining conditions for the purpose of allowing an operator to select at will the conditions under which the function of automatically correcting machining condition works, and a numerical control information correcting section, in which a machining conditions automatic correction command is provided, so as to perform machining conditions automatic correction at any time as required. As a result, since machining conditions are corrected automatically by correcting numerical control information, an operator can set proper machining conditions easily even if the operator does not understand the relationship between the machining conditions and the generated numericaL control information.

  • Patent number: 5251143
    Abstract: An NC program generating apparatus corrects the start and end points of a machining command with suitable patterns obtained by automatic judgement, as well as checking whether or not interference with the part shape occurs to thereby easily form an NC program which is free of collision, excessive or insufficient cutting or the generation of fins.
