Abstract: | Factors such as cutting speed, feed rate, tool material, etc., are well known to have an effect on tool wear in metal turning. However, reliable methods of wear prediction over a broad spectrum of cutting circumstance remain elusive, suggesting that not all factors have been recognised as significant and thus considered. This paper demonstrates that one such factor is bar diameter. The findings are analysed in three separate ways. All tests were performed under identical cutting conditions, i.e. cutting speeds were constant as well as the feed rate and depth of cut, also the same bar was used except for varying the bar diameter. All experiments were performed in single point turning on solid carbon steel bar (BS970 080A42), by using uncoated ISO (4957) (BS 4659 BT42) HSS insert. |
