Abstract

The Objective of this project work is to Productivity and Surface finish improvement in CNC Die and Punch machining through optimization in cutting parameters. This technical paper studies the different machining parameters i.e. DOC, cutting feed and cutting speed by using different material cutters like cemented carbide cutters, HSS cutters, Insert types cutters. In this thesis an attempt to make use of Japanese optimization technique to optimize cutting parameters during high-speed milling of aluminum alloy using cemented carbide cutting tool.

Introduction

I. INTRODUCTION

A. Study  Of   Process  Parameters  in  Machining

For any machining or metal cutting operation, three relative   motions  between the work piece and cutting tool  are   indispensably  necessary  for  gradual  removal of  material  from the work piece. In fact, the simultaneous  action  of  all  three  relative  motions causes  advancement of cutting tool towards work material  along  the  intended  path  generating    a  finished  surface  with  intended  shape, size and tolerance.  These  three  relative  motions are  called Cutting, Parameters Such parameters directly affect machining performance .

II. PROBLEM STATEMENT

In Enhance Surface Finish And Productivity In CNC Die And Punch Machining Surface Finish Not Meet Requirement, We Not get The Surface Finish  In Surface Finishing of Complex Shape Components ,inaccessible area geometry try and Difficult to Machine Material The process itself is very complex, The efficiency And Performance of will be improved by Taguchi Method. 

III. OBJECTIVES

1. To improve Appearance .
2. To wear and Tear .
3. Increase Durability .
4. To Avaid Corrosion .

IV. FUTURE SCOPE

It Increase the range of suitability ,Specifically allowing cheaper metals to be used in place of more expensive ones . Surface Finish refers to the texture and Smoothness of the Machined parts exterior . It’s a critical parameter that affects not only the appearance but also the mechanical properties and performance of the part.  Controlling the Surface finish Manufacturers can enhance corrosion resistance , reduce friction improve sealing capabilities and ensure  the part meet the required specification for its intended application 

V. LITERATURE SURVEY

The Objective of this project work is to Productivity and Surface finish improvement in CNC Die and Punch machining through optimization in cutting parameters. International journal of scientific research- “Optimization of Milling Process Parameters using Taguchi Parameter Design Approach.” This technical paper studies the different machining parameters i.e. DOC, cutting feed and cutting speed by using different material cutters like cemented carbide cutters, HSS cutters, Insert types cutters. International journal of innovative research in science, engineering and technology- “Optimization of Milling Process Parameters of HSS using Taguchi Parameter Design Approach”.

In this thesis an attempt to make use of Taguchi optimization technique to optimize cutting parameters during high-speed milling of aluminum alloy using cemented carbide cutting tool. The cutting parameters are cutting speed, feed rate and depth of cut for milling of work piece aluminum alloy. In this work, the optimal parameters of cutting speed are 2000rpm, 3000rpm and 3500rpm, feed rate are 200mm/min, 300mm/min and 400mm/min and depth of cut are 0.2mm, 0.3mm and 0.4mm. Experiment is conducted by considering the below parameters. Cutting forces, surface finish and cutting temp. are validated experimentally. welding process.

Conclusion

For 25 Mm Dsiameter Cutter 1) For smaller die-punch machining of the size 300×150×60 or less, the optimum parameters for getting N6 surface finish is 0.3 mm step-over with a feed-rate of 1800 mm/min. • This will result in better surface finish and decrease in average surface roughness by 0.108µm. This will result in saving in production time by 16.71%. 2) For bigger die-punch machining of the size 500×300×80 or more with large overhang (l/d ratio), the optimum parameters for getting N7 surface finish is 0.4 mm step-over with a feed-rate of 1500 mm/min. • optimized parameters will result in saving of 24.96% of production time. This will result in increase in average surface roughness by 0.21µm which is almost negligible compared to substantial increase in production time.
