Analisa keausan pahat pada pemesinan bor magnesium AZ31 menggunakan metode taguchi

Abstract

hisel rotating on a workpiece. During the machinery process happened
interaction between the eye drill with a workpiece where work truncated
while a jackhammer experienced friction. Friction experienced a chisel
coming from the surface upset that flows and the surface of a workpiece that
has been lopped off, due to friction this chisel had worn out. The purpose of
this research will analyzes age use a chisel hss in pemesinan drill magnesium
az31 and to support the survey used method of taguchi to analyze pembahsan
the results of the study. Machinery parameter a drill that is used namely a
jackhammer hss ( hight speed steel with size ( 10 mm, 12 mm, and 14 mm ),
the pace lap ( 635 rpm, 970 rpm, 1420 rpm ) and used motion a meal ( 0.10
mm / rev, 0.18 mm / rev and 0.24 mm / rev ), with a depth cut 50 mm. the
data wear a chisel carried out using a microscope digital usb with event 50x.
Data wear chisel seen every time one drilling process and machinery process
will be stopped if a drill bit has made out. The results showed that chisel
highest age profits to drill diameter 10 mm and the pace lap 635 rpm and
use motion eat 0,10 mm / rev which was during 12,74 minutes, while age
chisel lowest diameter drill obtained at 14 mm and the pace lap 1420 rpm
and use of motion eat 0,18 mm / rev which was during 0,68 minutes.Based
on analisys of variant ( anova ) that parameter most significant in
mempengaruh age wearing a drill bit is the pace lap ( n ). The greater the
pace lap ( n ) and wear a drill bit will be more quickly, this is because high
temperatures in the result of friction between screw eyes and workpiece.
