The development of the structure and mechanism of digital production system (DPS) functioning during technological preproduction (TP) and adaptive control (AC) of preliminary finish turning and milling is presented. On the basis of the analysis carried out with the use of complex criteria of technological cost price and general effectiveness of equipment there was defined an increase of technical and economic TP effectiveness of machining at the expense of the measures offered for DPS introduction.

Lower Limits

The objective of the study was to determine the limits of economic justification for irrigation system capacity use. The first step was focused on determining the lower limit of capacity use by comparing the economic effects of irrigation with the costs of the irrigation system use. In addition, while determining these limits the need was stressed to consider the economic effects of irrigation by optimizing the production structure and the modes for limit determination under irrigation and non-irrigation conditions. Eventually, the empirically verified possibility stating that this limit may be determined by comparing the water processing prices with its cost price is given. The limit was found to be the point at which these two prices equalize.

Further Development

The low workability of special brands corrosion-proof, heat resisting and high-resistance steels and alloys, widespread in details and nodes of modern machines, causes high labour input and the cost price of their manufacture. In this connection probes of possibilities of heightening of capacity and lowering of the cost price of handling of these materials at the expense of improvement of working conditions of the cutting instrument and, in particular, at the expense of application of various technological cutting fluid (TCF). High temperatures in a workpiece range, arising because of low heat conduction of intractable materials, define necessity of probe of the temperature phenomena for a cutting zone. The further development of a technique of definition of temperatures is of interest for these aspects of materials in a cutting zone at use ТСF and the account of their influence on a choice of optimum conditions of cutting. Researches of limitations on the roughness of the treated surface and cutting temperature are executed, in-use during optimization of cutting regimes at finish turning stainless materials, including with the use of technological cutting fluid. Analytical dependences of optimum cutting serve and speed from the parameters of finish turning process are set, providing the quantitative estimation of possibilities of the cutting regimes increase due to application of TCF. The estimation of efficiency of TCF application is executed on the basis of coefficient of increase of the treatment productivity.

The Creation

Nowadays, Japanese manufacturers are deploying global production based on the concept of "uniform quality worldwide and production at optimum locations". In an effort to realize this, the authors have proposed Advanced TPS, and recognized the necessity of "the creation of a new, human-centered production mechanism". Furthermore, the authors have also proposed "HI-POS". In this paper, an implementation method of "HI-POS", the "HDP" method has been established, enabling a total linkage from designing to manufacturing through a digital pipeline. More specifically, it is (1) a digital production system which prepares the work procedure in advance, and also it is (2) a production system which verifies a line process setup in advance. This accommodates the production planning needed for manufacturing a number of models on one line and completes the building up of the line even before launching it. The authors have been studying the validity of this method at an advanced manufacturing corporation, Toyota Motor Corporation. The use of this method has enhanced the skill level of production operators and thus yielded the expected results.
