Multi-functional tooling for the machining of rotational features such as: turning, grooving and proling operations – having excellent chip control. [Courtesy of Sandvik Coromant] . Chapter serts, with improved insert security its toolholder location, • CNC programming simplied – many tooling man- ufacturer’s have specially-prepared soware to sig- nicantly reduce CNC programming input times. NB is latter point utilises CNC ‘canned cycles’ to reduce program lengths. In Appendix 3, a guide for ‘Trouble-shooting for turn- ing operations’ are listed, with possible causes and rem- edies to potential production problems. In the following chapters, many other important chip-forming production processes will be discussed, with hole-making techniques such as drilling being around 25% of all manufacturing techniques under- taken by machining-related companies – these and associated hole-production methods will be reviewed next.
