TiAIN%arc ion plating%honing treatment%high speed machining%tool life
The objective of this work is to compare the tool performance of TiN and TiAIN coated carbides end-mills deposited by an arc ion plating (ALP) method, using honing treatment to polish the cutting edge surface sleekly. The curve of surface roughness versus honing time showed a rapid improvement initially and thereafter became steady, manifesting a saturation effect. The optimal honing time related to surface roughness was determined to be approximately 20 s. As the surface roughness increased, the critical loads reduced. At an average surface roughness (Ra) of 0.028 μm, the highest critical loads of TiN and TiAIN coating layers were 98 and 114 N. respectively. Tool performances of uncoated and coated tools were conducted under high speed machining (HSM) of AISI D2 cold-worked die steel (62 HRC). Consequently, the TiAIN coated end-mill using honing treatment showed excellent tool life under HSM conditions.
