Abstract

A fixture is a work holding device which holds and positions the work, but does not in itself guide, locate or position the cutting tool. The milling fixtures so far are generally used on milling machines. The present volume of this paper includes the unique aspect of designing of a 4 axis 360o indexing milling fixture for CNC. This fixture provides locating and clamping provisions for as large as 28 numbers of operations to be performed on support plate, one of the components of color mixing machine. The real time application of the research reflects from the fact that a real industrial component is taken for fixture designing. The designed fixture has the important characteristic of allowing all 28 operations to be performed on component in a single set up. Time estimation sheet for each operation is included, which also covers the details of type of tool & inserts to be used with data of cutting speed, spindle speed, feed & no. of passes required to accomplish the operations. 3D exploded view of fixture in addition to 2D & 3D drawings of component and fixture using Pro/Engineer are also included.
