Description
Technical field
The invention belongs to part processing technique fields, and in particular to a kind of processing dimension towards multistage manufacturing processes system is inclined
Difference control method.
Background technique
Product size deviation refers to that product is influenced by various deviation sources in process, as part passes through production
Line, dimensional discrepancy are constantly be generated, accumulate and transmit, and ultimately form difference in offset of the actual size relative to design size of product
Value.Because product size deviation is to directly affect one of the most important factor of product quality, productivity and market response time etc.,
So it is always the key points and difficulties of domestic and international academia Yu industry research, however, in production, the complexity of process
Property inevitably results from, transmits and accumulates dimensional discrepancy.
As production process becomes increasingly complex, product, which passes through a case where procedure just completes the process, to be become seldom, and is produced
Quality is influenced by multiple deviation sources.The system of processing of complex product is often one parallel with the multi-source serially combined
Multi-process system, during end product quality is subject to processing on all process steps multiple deviation sources influence, in addition to single process
On various deviations outside, as part material characteristic, tooling device, fixture elemental characteristic to product deviation generate it is different degrees of
It influences, there is complicated coupled relation between different processes, and deviation may be introduced, these mass deviations constantly generate, transmit, increase
Long, abatement, accumulation and transmitting, form the dimensional discrepancy of final products.
