Pengaruh Tipe Pahat Dan Arah Pemakanan Permukaan Berkontur Pada Pemesinan Milling Awal Dan Akhir Terhadap Kekasaran Permukaan
Abstract: The product of
process machining by milling to mill contour or pocket is usually started with
process of roughing by 3-axis milling base on desired contour, in this process
we selected depth of cut (DOC) and height of scallop and than did process
finishing by 5-axis milling to eliminate scallop from process roughing, in this
process we selected scallop without DOC. The feed directions in finishing are
in-line and across direction and tools used were flat, toroidal and ball nose
end mill. Each type of tools and feed direcrion in process roughing and
finishing will influent difference surface roughness. This research is to
analyze influence of type of tools and feed direction machining roughing and
finishing to the surface roughness resulted by milling machining. Examinee
factor is two types of tooling roughing ( end mill flat and toroidal), two type
of tools finishing (toroidal and ball nose), two types of feed direction (
in-line and scross) and we measured roughness as respond datas. The attempt
full factorial is =8 variation. Result analysis of variance (ANOVA) indicate
that the type of roughing tools, type of finishing tools and feed direction
statistically have an effect on surface roughness.
