Abstract
The topic of this graduation design is the design of processing planning，tooling
devices and CAD/CAM for installation seat （ 6422635 ） , which comes from Wuxi
Impro (China) Co, LTD.According to the company's production capability and
equipment cases, the designer has completed the investment mould of parts, the process
planning of parts and special fixture. On this basis, based on CAD / CAM technology,
the designer has completed the machanisms simulation of fixture.
On the basis of introducing investment mould, process planning, and mould
CAD/CAM as well as its advantage, the thesis describes design contents and methods of
the investment mould design, process planning and special fixture in detail. Thereinto,
mold design mainly has three-dimensional design of solid parts, the mold parting
surface design, mold tooling interference analysis, and the design of gating system,
positioning and fastening device mechanism. The process planning design contains
selection of the process, positioning and fastening device ways, machine tools and tools,
the computation of cutting dosages and the formulation of process route. Moreover,
fixture design solves the problems such as the positioning error analysis and clamping
force analysis, and so on.
Finally, the thesis introduces the machanisms simulation of fixture, which includes
the machine tools and tools selection, cutting parameters settings, process simulation
and analysis of the spindle speed, etc.
In a word, basing on process planning and tooling devices design theory for the
parts, this paper has carried out the practical application of the installation seat
（6422635）parts investment mould, process planning and tooling devices design, and
