Rapid profiling machining operation method for new sample piece of automobile engine part

Abstract

The invention discloses a rapid profiling machining operation method for a new sample piece of an automobile engine part, and belongs to the technical field of automobile engines. The processing quality of new products can be ensured, the trial-manufacturing efficiency of the new products is improved, rapid conversion from three-dimensional digital analog to sample pieces is realized, and the development cost of the new products is reduced. The method comprises the following steps: S1, selecting a blank; S2, making a blank digital model; S3, making a processing scheme; S4, determining a machining process, and selecting a cutter; S5, writing a processing program; S6, designing a clamp; S7, clamping the part; S8, aligning a workpiece coordinate system; S9, calling a machining program to start front face machining; S10, conducting turn-over machining, and repeating the operation steps from S3 to S9; S11, carrying out natural aging for 150 hours; and S12, performing finish machining on each surface and each hole through manual programming to finish machining of a final new sample piece. The machining efficiency of new products is effectively improved by 30% or above, operation is convenient, the alignment frequency is reduced, and adjustment is easy.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and in particular relates to numerical control machining of automobile engine parts. Background technique [0002] There is no mold blank in the trial production stage of the new automotive engine sample, so only rapid prototyping blanks can be purchased for supplementary processing or finished samples, which has a long cycle and high cost. [0003] After the new product sample is assembled and tested, the structure of the part may be properly trimmed. It is necessary to repeat the design, procurement and processing of the new product sample, which will increase the manufacturing cost and prolong the production cycle. [0004] Automobile engine shell parts are mostly thin-walled parts, easy to deform, time-consuming and labor-intensive to process, and difficult to guarantee accuracy. With the application of numerical control technology, CNC machine tools are currently used for processi...

[0003] After the new product sample is assembled and tested, the structure of the part may be properly trimmed. It is necessary to repeat the design, procurement and processing of the new product sample, which will increase the manufacturing cost and prolong the production cycle.

[0004] Automobile engine shell and disk parts are mostly thin-walled parts, easy to deform, time-consuming and labor-intensive to process, and difficult to guarantee accuracy. With the application of numerical control technology, CNC machine tools are currently used for processing, but it is easy to produce processing stress and deformation, and the processing accuracy is not ideal
