Abstract
The aim of this publication is to determine the OEE (Overall Equipment Efficiency) indicator for 5 axes milling machine found at Diehl Aircabin Hungary Ltd. for the present and future state. Based on this value, the utilization of the machine for the given production amount can be calculated. With the optimal choice of the right production parameters (the number of cuts, feeding, depth of cut, etc.) greater productivity can be achieved i.e. the machine main time (time of cutting) will be less. The possibilities of the reduction of the machine time will be analysed and calculated. Setting of the appropriate technological parameters the machine main time could be decreased. The calculation of the machine main time will be determined for the most frequent manufacturing technologies.
Highlights
LEAN is an organizational company conducting system which aims to produce its products and services by the most economical way
The calculated OEE indicator is above 100%, which means if there is that high production volume, one MAKA type CNC milling machine will not be sufficient for production
We have determined the OEE indicator values for MAKA type CNC driven milling machine having 5 axes found at Diehl Aircabin Hungary Ltd. for the period of 2015 and 2016
Summary
LEAN is an organizational company conducting system which aims to produce its products and services by the most economical way. A LEAN company targets its activities on the customers’ needs, and what they perceive as valuable. Those things which are not of value for the customer, and for which they are not willing to pay, LEAN system takes as loss, and increases the efficiency of the processes by ceasing these losses or reducing them to the maximum [4], [5]. At Diehl Aircabin Hungary Ltd. doors – doorframes, side elements, climatic tubes for Single Aisle (shortterm travel) and Long Range (long-term travel) airplane types are produced (Figure 1).
