Effect of Rake Angles on Tool During Orthogonal Metal Cutting Process For Different Materials Through Ansys

the process of orthogonal metal cutting is analyzed using the Academic FEA package ANSYS/Explicit 14.5. The focus of the results presented in this paper, effect on tool by different rake angles and depth of cuts in orthogonal metal cutting process. A number of finite element simulations have been done with the ANSYS/Explicit Dynamics 14.5 to initiate the stress variations on tool during orthogonal metal cutting process. A tool rake angle varying from 20o, 25°, 30o and a friction coefficient is constant 0.4 mm and constant cutting speed 2.54 m/s with depths of cut are 0.05, 0.1, 0.15 mm has been considered in the simulations. The results of these simulations provide insight how stresses are influenced by rake angle and depth of cuts.

Enhancement of Productivity through Analysis and Modification of Existing Plant Layout at a Manufacturing Firm

With increasing demand in production, industrial factories must need to increase their potentials in production and effectiveness to compete in markets. Therefore, the way to solve the problem relating to the production is very important. This study of plant layout is done in B. Shankara Sales Organization, Agra which is a piston and piston ring manufacturing company of two and three wheeler vehicle. Throughout the study, the aim is to proposed new layout to this company to increase their productivity. In each workstation the processing time is different and the longest time consumption is workstation will be identified as a bottleneck workstation. The time is taken by stopwatch of each and every machine in the cell. In this study, application of Computer Aided tools is introduced which in this study is ARENA software. The related inputs are going to be simulated with this software. The goal of the thesis is to seek the best layout in terms of increasing productivity rate hence proposed

Wear Analysis of Multi Point Milling Cutter using FEA

The material removal process uses cutting tools in order to produce the desired shape of the work piece. Tool wear has been a problem for cutting tools, since cutting tools wear and break. Research has been accomplished in the tool wear field for tool life and more recently tool wear. The computer generation has created a method to simulate the material removal process. These computer simulations model the cutting tool reaction with the work piece. Many of the simulation models use finite element analysis to calculate the reaction of the cutting tool. Different finite element models are being used throughout the world for research. In this Paper the design aspects of surface milling cutter is analyzed. The objective considered is the design and modeling of surface milling cutter and to analyze various stress components acting on it. Various designing strategies are considered to design the effective surface milling cutter like outer diameter, inner diameter, radius, teeth angle etc .The design and analysis is carried out using the software like Pro-E and ANSYS

Investigation of design parameter of two wheeler frame through comparative analysis

Now a day there are mainly two types of frames developing one is square frame and other is tubular frame. In this work we will going to be compared what are the mechanical differences between a tubular and square (no tubular) frame and trying to take some conclusions. In this research we took two materials which are used mainly in two wheeler frame. That is aluminium and steel. We used Creo for modelling and ANSYS for analysis.

“Enhancement of Productivity at Sai Nath Fastners Through Lean Tool’’: PDCA-Demmings Cycle

Lean Concept has a good reputation of uncovering waste in manufacturing, survey production and business process by identifying, calculating and removing non value adding steps. Over all Lean is an easy method of recovering a product’s production path from door to door and to various machining operations. In a process survey is done where all non value added actions are searched and identified in each step and between each step there is estimations of its wastage time and resources are identified. Manufacturers face challenges in efficiencies in their manufacturing operations.

Impact Analysis of Car Front Bumper to Enhance Crashworthiness

Bumper is the important part of an automobile vehicle. It used for safety of various front parts of vehicle as well as protection of occupants also from collision of vehicle. We know that the death in accident is very common not only in India but in the world. So the safety of occupants and passengers are primary criteria at the time of vehicle design and bumper play a vital role in safety of occupants. In this research we try to improve the impact strength of an existing car bumper by material optimization in economic way. We also emphasis on the light in weight of bumper to reduce the gross weight of vehicle which is very essential to increase fuel efficiency of vehicle. Creo used for modelling the existing bumper and ansys 16.0 used for meshing and calculation of stress & deformation at FMVS (federal motor vehicle safety standards) velocity13.34m/sec (48kmph) and at IIHS (Insurance Institute of Highway Safety) velocity17.78m/sec (64kmph) with existing material GFRP and suggest the best material for replace the existing material to improve the overall performance of vehicle on the difference criteria.

Improving Predictability by Blending VSM with KANBAN

Value flows in every process, and early days was of focusing on Value Addition at every such intermediate stage of process. However, with evolution of KANBAN, JIT under the umbrella of the Toyota Manufacturing System (TMS) emphasized on eliminating waste i.e. Muda( A Japanese Term for Waste, Commonly used in Toyota Management System) and gradually Value Addition is replaced with evaluating Process as a Value Stream and Mapping critical activities. VSM, has become a significant tool these days to analyze, evaluate Process from Status Quo to carve it future State by eliminating inherent Waste(Muda) within the process. Keywords— Kanban, JIT, Muda, TMS, Value Stream, VSM, TPT, Takt.

Assessment of Environmental Impact: Sub Assembly ‘Cam Shaft Valve’ of Engine Group of ‘two-wheeler’

The investigation of environmental impact of products and processes has become a key issue. The environment has some capacity to absorb these emissions so emitted to a certain level without lasting the damage. All products have an impact on the environment during their life-cycle spanning all phases from cradle to grave. The emissions have harmful effect at local, regional and global levels. LCA is a means of deriving a quantitative evaluation of environmental impact of product design and thereby refining product quality and characteristics. Now a day, a major part of our society using the two-wheeler in large quantity and its becomes the necessity of day to day life. This work deals with the investigation of some parts of product, i.e. ‘cam shaft valve’ assembly of two-wheeler for environmental impact assessment through using scientific approach of Life Cycle Assessment (LCA). The assessment has been carried out for three main stages of life cycle of the product. LCA method considered for this work is Environmental Design of Industrial Products (EDIP). It is observed that, as per the method used Eco-toxicity, human toxicity and global warming is more as compared to other impact categories.
