Abstract
The paper aims at designing and fabrication of gear cutting attachment to lathe. In the present work, I made an attempt to design and fabricate an attachment for a gear cutting for a medium duty lathe. This attempt will reduce the investment for medium and small scale industries, sub sequent reduce the manufacturing cost of gears. The attachment to lathe can perform an indexing mechanism like milling machine and carriage function, to and fro movement and sliding on a bed. The attachment was mounted on carriage, where we fixed the work piece and a mandrel was designed to hold the cutting tool. This mandrel was attached to the head stock spindle which is the main source for rotation of the cutting tool. The attachment was carefully designed after studying the proper mechanisms, power requirements and force analysis on work material and a cutting tool
