ANALYSIS OF THE DEVELOPMENT TRENDS AND POSTPROCESSING OF ADDITIVELY PRODUCED PARTS
Abstract
The subject matter of the study in the article is the analysis of the state, trends and prospects for the development of additive production of metal parts in the aerospace field. The article discusses the need for the application of post-processing processes of additively produced parts; the necessity of parts cleaning after printing is determined, the processes of gas mixture ignition and thermal pulse cleaning as a whole are considered. The goal is to review the application of the additive manufacturing process and the cleaning technology for finished products. In this regard, the following tasks were set: analysis, review and determination of the development trends of additive manufacturing, post-processing of parts and the thermal pulse cleaning process in particular. The following results were obtained. The main areas of practical application of metal parts additive production are analyzed. The technological processes features of post-processing of surfaces and parts as a whole are considered. Based on the above examples, the need for the use of a blank cleaning process is substantiated. In the context of existing cleaning methods, the features of thermal treatment are considered, namely: the essence, advantages and processes accompanying it. Highlighted the current issues of the appointment of technological processing parameters. The following conclusions are formulated. Additive manufacturing is a fast-growing and promising method for the production of parts in the aerospace industry in view of its manufacturability and economy. Thus obtained parts, usually, do not require additional processing, however, it is not always possible to completely get rid of its need at this stage of technology development. One of the most important performance characteristics of parts is the quality of their outer and inner surfaces. In this regard, the use of thermopulse processing is economically determined. To use all the potential capabilities of this cleaning method, it is necessary to study it more deeply in order to determine the influence of processing modes on its result.
