An Experimental Approach of Manufacturing Hardened Barrel Screw on Traditional Lathe Machine with Different Parameters

Barrel Screw is manufactured by CNC Milling Machine. EN41B Chromium, Molybdenum nitriding steel alloy is used as raw material the initial hardness is round about 250 to 300 HRC. Now the problem is screw manufacturing cost on CNC Milling Machine is too much high normally 1.25 lacs to 1.50 lacs depending upon it’s screw profile consumers have to pay high cost. The researcher focus how to reduce the cost of production of barrel screw. The certain changing of parameters has been made on traditional lathe machine. In CNC Milling Machine the manufacturing process is followed by programming the path as well as the selection of process and the same milling attachment live supporting rest, and end mill cutter is used. One specially designed milling attachment is installed on lathe carriage, one other Indexing Mechanism is attached with lathe main spindle.There after the machining process has been carried out looking to traditional lathe machine the manufacturing cost incurs 35 % less than that of CNC Milling Machine. Researcher made the sample barrel screw on lathe as well as on CNC Milling the conclusion is less in cost round about 35 %. The quality, profile and finishing of screw is also achieved on lathe machine and inspection report indicates that the quality is same and so we can say that on traditional lathe machine by changing different parameters. We can manufacture same economical barrel screw less than 36 % in cost reduction compare to CNC Milling.
