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 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. 0aMachining 0aMachiningxAnalysis
