Thin-walled parts is composed by various thin board (shell) and the tendons of strengthening as a lightweight structural parts.It has a advantage of light weight,high
strengthly and aesthetically.As well as that,the structure of thin-walled has a widespread application and it was commonly used by aerospace products.Because the structure has a request of lightweight parts,the large number of aluminum alloy and titanium alloy are commonly used as a low density of the material.Thin-walled structure have a lot of problems in the manufacturing process,such as deformation,buckling and vibration caused by cutting force,clamping force,because of its relatively low stiffness,poor processing technology.It is extremely difficult in the process of manufacturing.Deformation in machining had an important role in the aviation manufacturing technology,and it has seriously impeded the development of the aviation industry.Therefore,we are studying the way of reduced deformation in machining,which has a great value of theoretical and engineering applications.
This text according to UG and craft analysis, gather a model, craft and Be processed to through an establishment the number of integral whole controls to process a chain, solution transforms, lead slice, slice to pare parameter absurdity etc. physically process medium often meet of problem, finally acquisition efficiently, the number of high mass control to process procedure, and pass experiment to income the procedure carry on a verification.Main studying and research conclusion are as follows:
1.adoption the UG reconstruct a mold to the parts progress, combination the structure characteristics of model type with physically process experience, processing of establishment reasonable craft, choice reasonable of slicing and paring parameter.
2.studied the craft of parts to draw up a method.Take common parts as foundation, the combination aviation thin wall parts carries on craft analysis to this parts, and complete the establishment of this parts craft.
3.studied to control an automatic plait distance according to the UG number.According to craft analytical with pattern structure characteristics, the knife potential of each born work preface track, acquire a knife potential document.Elaborate to postpose the calculate way priniple of the disposal and the condition of its demand, and set up to meet to request of postpose processor.Postposing a disposal to the knife potential
document progress is suited the G coded document of the engine bed.
