| Summary: | This paper presents the suitable depth of cut,
spindle speed and feed rate that will be chosen during
machining. If thus parameters are not considered, this
can provoke abnormal tool behavior such as chatter.
Chatter will limit the tool life which only can be use for just a few times. To predict the chatter occurs, the
parameters will be use are spindle speed, depth of cut
and feed rate. CNC machine will be use. This process
will base on dynamic cutting force model for ball end
milling. The selections of cutting tool are depends on the process that will done where the chatter can be observed during this machining process. Cold work tool steel (AISI-D2) chosen as a material and its parameter is
100x100x25 mm. Cutter used was high speed steel 2 flute
ball nose. Force dynamometer will be use to measure
force and 27 tests will be done to observe the chatter
occur. Analysis done by referring the result that be
measured by force dynamometer. The chatter in ball end
milling can be detected from the calculated cutting
forces and their frequency spectra. A comparison of the
predicted and measured cutting forces demonstrated
that the proposed method provides accurate results. |
