Kesan parameter pemesinan ke atas pembentukan serpihan semasa mengisar hujung keluli terkeras aisi H 13 menggunakan mata alat sermet
The effect of machining parameters on chip formation during end milling AISI H13 tool steels using cermet inserts was investigated. The machining range were set at speed of 224- 355 m min-1, feed rate of 0.1-0.25 mm tooth-1 and radial depth of cut of 0.3 -0.8 mm. The SEM analysis shows that'...

| Summary: | The effect of machining parameters on chip formation during end milling AISI H13
tool steels using cermet inserts was investigated. The machining range were set at
speed of 224- 355 m min-1, feed rate of 0.1-0.25 mm tooth-1 and radial depth of cut of
0.3 -0.8 mm. The SEM analysis shows that' chip formation strongly depends on the
depth of cut and feed rate rather than on the cutting speed. At low machining
conditions at speed of 224 m min-1 feed rate of 0.1 mm tooth-1 and radial depth of cut
of 0.3 mm, discontinuous chip with smooth edges was produced, whereas at high feed
rate of 0.25 mm tooth-1and radial depth of cut of 0.8 mm, saw tooth chips was
formed |
