Abstract

Selecting the most suitable work equipment is a key factor in creating the value of products; therefore, the design and selection of work equipment are increasingly focused on its adaptability. The adaptability of work equipment with regards to flexibility and responsiveness is defined by its universality, mobility, modularity, compatibility and economy. This article presents a methodology of evaluating the adaptability of work equipment and a procedure for selecting work equipment with the maximum adaptability index (i.e. the optimal one) from a group of available work equipment. The results of designing and weighing the criteria of the target tree are presented, as well as the results of coarse and fine selection of the optimal CNC lathe, considering its expected adaptability.

Highlights

  • The production programmes of small and medium enterprises are subject to continuous changes and ever increasing customer requests for the shortest possible delivery times, the best possible quality and the lowest possible product prices

  • Adaptability consists of the flexibility and responsiveness of work equipment; this can be classified under universality, mobility, modularity, compatibility and economy

  • Adaptability of work equipment in the form of flexibility and the responsiveness of work equipment is defined by the universality, mobility, modularity, compatibility and economy of work equipment [5]

Summary

INTRODUCTION

The production programmes of small and medium enterprises are subject to continuous changes and ever increasing customer requests for the shortest possible delivery times, the best possible quality and the lowest possible product prices. Companies are faced with unstable demands regarding the types and quantities of products Due to these demands, frequent changes of functions and the layout of work equipment are required. Adaptability consists of the flexibility and responsiveness of work equipment; this can be classified under universality, mobility, modularity, compatibility and economy. Flexibility means that the work equipment is greater than needed with respect to the current functions, performance and accuracy. It allows the management of future, planned-in-advance scenarios. The responsiveness of work equipment is the capability of reacting to new circumstances that were not foreseen in the planning phase Such a responsiveness is carried out by using its capability of being reconfigured. An exact specification of the work equipment adaptability is required
