Technical-Economic Aspects of the Use of Technological Process of Deforming Broaching

Abstract

The article gives a definition of the technical and economic potential of the application of the deforming broaching process. Research of the consequences of introducing deforming broaching into technological processes at manufacturing enterprises is carried out on the basis of application of system resource and matrix approach. On the basis of the performed researches, a methodological basis for the economic evaluation of the results of applying deforming broaching on the production has been developed. The article has improved the well-known scientific and methodological foundations for the determination of technical and economic results of the application of deforming broaching due to the complex identification of production-organizational decisions -in technical and forms of evaluation in economic spheres. The developed approach gives an opportunity to more accurately assess the economic effect of introducing deforming broaching on the mining, metallurgical and machine building industries. It can be used to assess the economic effect of introducing other process parts processing.

Designing the structures of discrete solid­alloy elements for broaching the holes of significant diameter based on the assessment of their strength

“…However, for technological reasons, it is not always possible to implement the condition h 1 /h=0. Otherwise, one should evaluate the effect of this parameter on the structural strength based on dependences (2) and 3, obtained when varying the values of the insert protrusion size over the body.…”

“…One of the main tasks of modern machine building is to devise and implement resource-saving technologies to im-prove the quality of articles [1]. Deforming broaching (DBR) is a highly efficient and economical operation in the machining of holes [2] and is used both as the draft and finishing operation, including the processes of shape formation and…”

The use of deforming broaching for ­enhancing the efficiency of cutter chisels

“…At the same time, the number of replacements of the treated crowns is by 4.4 times less than of the serial ones. The economic effect of the implementation of the de veloped technological process is largely determined by the durability of reinforced cutters and makes up 480 000 UAH per 100 cutters [1].…”

“…The process of deforming broaching is used: for machining deep bores in tubular work pieces and cylindrical nodes; in restoring dimensional accuracy and machining pis ton pins and crosspointing hinges; diamond drilling extend ers, casings of break cylinders and hydrocylinders and so on. The positive technicaleconomic properties of the deforming broaching process make its further spread in mining, coal, gas, metallurgical and machine building industries expedient [1].…”
