Simplified Methodology for the Design of Technological Support for Laser Treatment Operations

Kotlyarov, V.P.; Kiyaschenko, A.N.; Sergiyenko, N.I.

While designing a technological operation with a lot of criteria estimation of its results, one of the stages of the procedure – choosing a technological schedule for its implementation, is complicated by the necessity of using one of the indirect optimization techniques, which is performed by experimental modeling of processing with combining the response functions by one or another way. This method of searching for the processing mode is not only complex and long-lasting but most often is ineffective when using a value of a higher level of complexity as an index (indexes), for example, the accuracy index of the dimensional results of an operation. A modified optimization algorithm is proposed that simplifies the content of the factorial space by eliminating the critical values in searching for the optimum processing mode. The influence of those values is compensated by changing the strategy of the technological operation, in particular, by using the method of "fitting" the critical index to the required level with a controllably decreasing increment of its value. To implement various operations with an adaptive form of their organization (precision hole machining, formation of dimensional slits, surface heating with the normalized depth of the zone), a number of technological installations and devices have been developed, the schemes of which are given in the article together with the results of their studies. Their application improves the indexes of the reproducibility of results of processing with a simplified procedure for selecting the technological procedure for operations.
