Abstract

dan  Adi NugrohoJl.  Grafika  No.  2,  Kampus  UGM,  Yogtakarta  55281AbstractThis paper  presents the  development  of  automatic casting  design  system for Taperlockpulley  type.  This  system  is  intended  to  assist  casting  designer  in  pattern design,  to  reduce  designtime,  and  to  minimize error  in  transfering  product  design  data into  pattern  design.The input  of this  system  is  data  base  of taper  lock  pulley's  catalogue  in  mdb format, whilethe  output  is  design of the  pattern  drawing  in  2D and  3D  solid. Moreover to  generate  patterndesign  is  around  59 second.Keywords:  casting,  pattern,  automat  ic.l.

Abstract

In small-size mould manufacturing industry, milling process is an important element because this process consumes the longest produclion time. AIso, milling process needs great investments in tools. Most of the small-size mould manufacturing industries uses manual-milling machine for roughing process. Manual milling machine is used because of capacity limitation of the CNC milling machine and high investment of CNC machines.A prototype of low-cost CNC retrofit milling system is developed in this research, to enhance manual milling machine capabilities, in accuracy, speed, and process complexity. The advantage of the prototype results in reduced manufacturing cost and reduced lead time. This research also compare the capabilities of the prototype to others milling systems.The prototype results in accuracy of X axis and Y axis respectively 0.013 mm and 0.009 mm. This system is capable to set the feed rate of minimum 1 mm/min and maximum 250 mm/min, depending on the material being processed.Keywords: prototype, retrofit, CNC milling
