Popis: The paper concerns the development of a computer-aided optimisation package for the minimisation of the residence time of a multi-component pallet being manufactured in a machining centre with a multi-tool facility. A methodology has been developed to take a part programme for the manufacture of many components which involves many tool changes, segment it, automatically re-sequence the machining order and regenerate it. Random input case studies have been used to demonstrate the ability of the software to minimise the number of tool changes and to find the near optimum tool path. A typical industrial case is given in the paper to show the ability of the software to reduce the residence time of a part programme. It is shown that the use of the computer-aided optimisation package with a range of part programmes reduced the pallet residence time by a factor between 4.6% and 32.3%.
