Aluminium Cutting Specific Issues
Journal Title: RECENT - Year 2011, Vol 12, Issue 33
Abstract
In this paper the difficulties of cutting pure aluminium, used mainly in large electrical contacts of high voltage equipment are presented. It can be noted that during the cutting without cutting liquid, at certain regimes, the chips are glued on the channel of the front face, remaining there and blocking the channel and cutting edge, so that accidents occur. Also, different forms of chips resulted after cutting with different regimes, indicating in each set of chips used in the cutting regime are studied. The microscopic images of chips, as seen from the outside and from the area that came into contact with cutting edge of bit are shown. The deposition under the cutting edge of bit after cutting at different cutting regimes and different geometrical parameters of used drawknife are presented. Images of cutting edges are given with elements of chips on them and microscopic images where the variation of deposit thickness and edge clearance are shown.
