DEVELOPMENT OF AN ADAPTIVE MACHINING SYSTEM FOR MICRO-DRILLING

An increase in the production of micro-components causes a need for the development of appropriate manufacturing techniques, one of which is deep-micro-hole-drilling. This paper presents the development of an adaptive machining system for deep micro hole drilling whereby adaptive control is recognized through thrust force. The drilling of 0, 5 mm diameter holes in special cast irons with up to 40:1 depth to diameter ratio is performed. Due to the problems related with micro hole drilling in respect to conventional drilling and expressive heterogeneity of workpiece materials, it is shown that the use of an adaptive control can be of significant improvement for insurance of an adequate micro drilling process.
