The performance of a turning process depends on various machining conditions which affect the surface quality achieved on the component, the tool life, cutting zone temperature and the metal removal rate. The turning operation produces the components, which have critical features that require specific surface finish. The wear rate of the single point cutting tool determines the cost of the process and also the quality of the component. The cutting zone temperature has detrimental effect on both the surface finish on the component and also the tool life. The turning process depends on a number of variables which include the machine tool, tool material and geometry, work material and cutting conditions. The variations in each of the output parameter for a variation in significant input parameter are analyzed graphically in this chapter. Detailed discussions on the machinability of the work material considered, the capability of the tool materials, the significance of the tool geometry and the influence of cutting parameters on turning process are described.

The ability to predict the surface texture of a machined part allows engineers to select appropriate process inputs such as cutting conditions and tool geometry during the design process, in order to control the required surface quality. In machining operations, the quality of surface finish is an important requirement for many turned workpieces. Thus, the choice of optimized cutting parameters is very important for controlling the required surface quality. The focus of the this work is to find a correlation between surface roughness and cutting vibrations in turning, and to derive mathematical models for the predicted roughness parameters based both on cutting parameters and machine tool vibrations. The correlation coefficient was calculated by collecting and analyzing data generated by turning mild carbon steel samples at different levels of speed, feed, depth of cut, tool nose radius, tool length, approach angle, workpiece diameter, workpiece length and tool frequency. An additional aim of the work is to find a mathematical model for the predicted roughness parameters, based on both cutting parameters and machine tool vibrations.

Simulation of Tool Flank Wear for Turning

4839 руб.
Economic selection of cutting conditions is an important task in the field of machining. The main problem faced in optimization of cutting conditions is that once selected the optimum cutting conditions do not remain optimum throughout the complete machining operation. This is due to the dynamic variations in the process parameters upon which the decision of optimization depends. So,there is a need to update the optimum cutting conditions continuously throughout the entire machining operation.To achieve this task the tool flank wear is measured by conducting experiments on lathe machine. The data values obtained from experiments are used to develop an equation for tool wear as function of speed, feed and time using Response Surface Methodology. This equation is used in simulation of multi objective optimization of turning operation.

Tungsten carbide (WC) is widely used in manufacturing industries because of its higher wear resistance property. The high hardness and melting point with excellent abrasive and corrosion resistance properties makes it most suitable for cutting tool industries. In order to increase the tool life efforts are being made to synthesize nano size WC powders through different techniques. In the present work WC nano particles were synthesize at comparative low temperature by thermo chemical route, and by mechanical synthesis route direct from the Wolframite ore. The synthesized nano WC powders were embedded in cobalt matrix and sintered. Cutting tool based on nano structured WC-Co particles will bring a revolutionary change in the development of cutting tool and also affect the cost of many other products related to the development of tool materials. The tool life is directly related to the size and distribution of WC particles in Co matrix. The reduced size of WC particles will lead more uniform distribution of it in Co matrix, which ultimately will lead to have more life time of cutting tool as compared to conventional material.

Zirconia Toughened Alumina (ZTA) cutting tool inserts were produced successfully by compaction method using nanosized 75 wt% pure alumina and 25 wt% pure zirconia powders. Raw materials were milled and mixed with binder and then tablet shaped cutting tool inserts were prepared using 300 MPa pressure and 1400-1450°C sintering temperatures. Microstructures of the tool were observed and important mechanical properties were measured. Cutting tool inserts containing as little as 2.94% porosity were being able to produce at 1450°C with the maximum true density 4.12gm/cc (compared to 4.38 gm/cc for theoretical density) and hardness of 11.45 GPa. An increase in sintering temperature produced denser and harder cutting tool inserts. The microstructure of sintered inserts showed zirconia grains dispersed in alumina grains, a structure that is usually obtained in this product. The cutting performances of the prepared ZTA inserts could not be quantified due to inappropriate tool holder geometry. However, from the data it is clear that this cutting tool inserts, when operated properly, would give a much better machining performance than the ordinary metal and metal composite cutting tool.

Present work is an experimental investigation is presented for accomplishing surface texture analysis using machine vision based system for measuring the condition of cutting tool. Analysis of machined surface images of different materials by turning and shaping process at different wear conditions cutting tool, grabbed using CCD camera are presented. An amplitude parameters based approach for analysis of machined surfaces is proposed. Machined surfaces with different wear conditions of the cutting tool i.e., sharp, semidull and dull are investigated by using surface metrology software and also with conventional method using stylus instrument for comparative purpose. However, considerably less work has been performed on the development of surface texture of machined work piece that provide information on the condition of the cutting tool, employed in machining the surface. A non contact method using machine vision is presented for inspecting surface roughness. A strong correlation between tool wear and surface roughness of the machined surfaces is found.It is proved that,this approach is effective in measuring the condition of the cutting tool through amplitude parameters.

Geometry of the cutting tools is one of the crucial parameters affecting the quality of manufacturing processes. The geometry of the surface generated on the blank is dependent upon the geometry of the cutter. This book outlines in detail geometric models of single-point and multi-point cutting tools and proposes a set of new three-dimensional (3D) standards for defining the tool geometry. The 3D geometric models of cutting tools would help the design, analysis and manufacturing processes of the cutting tools. Relations are developed to map 3D angles to equivalent conventional angles as detailed in ASA, ORS and NRS standards. This set of relations is known as forward mapping. Similarly, the relations to find 3D angles from the given conventional angles, inverse mapping, are also established. The setting or swivel angles for grinding and their relations with 3D rotational angles are developed for single-point cutting tool to generate features for resharpening. To illustrate the utility of 3D definitions of cutting tools, a few case studies on Finite Element based Analysis, CNC machining and geometric assessment of tool wear and defects of different cutting tools are considered.

This work relates to the application of Artificial Intelligence to tool wear monitoring. The main objective is to develop an intelligent condition monitoring system able to detect when a cutting tool is worn out. It is used a combined Expert System and Neural Network able to process data coming from external sensors and combine this with information from the knowledge base and thereafter estimate the wear state of the tool. The novelty of this work is mainly associated with the configuration of the proposed system. With the combination of sensor-based information and inference rules, the result is an on-line system that can learn from experience and can update the knowledge base pertaining to information associated with different cutting conditions. Two neural networks resolve the problem of interpreting the complex sensor inputs while the Expert System, keeping track of previous success, estimates which of the two neural networks is more reliable. In this study an on-line tool wear monitoring system for turning processes has been developed which can reliably estimate the tool wear under common workshop conditions.

DEVELOPMENT OF SIMULATION

In any machining process the economic objective is to maximize the metal removal rate by the highest possible feed rate under the constraint of tool breakage. An NC Program merely guides and controls a Machining process. It cannot respond and react to variations in machining conditions during the operation. Machining force regulation and tool wear are challenging problems since the force and temperature rise varies significantly under normal operating conditions. In order to overcome above mentioned problems, the concept of ADAPTIVE CONTROL MACHINING was introduced. Adaptive Control system (AC) maximises material removal rates and minimises cycle times by optimizing the cutting feed rate based on a controlled spindle load.In accordance to the results obtained, the application of Adaptive control principles to TURNING is aptly justified. As part of this work, a simulation is developed for turning process based on adaptively controlled experimental data.

Tool characteristics were examined with respect to the effects of machine controlled parameters and tool geometry on cutting phenomenon. This subject has been a matter of prolonged interest to machine tool designers and users alike as it is the basis on which tool life and hence general metal cutting economics are evolved. Previous research works concentrated on temperature generation usually without recourse to the combined effects of the machine controlled parameters and tool geometry. This missing link was supplied in this work. Basically, the findings of this work show that the cutting speed has a great influence on the forces and temperature and hence on tool life as well as the machining economics. The feed has similar but less influence on these quantities. The cutting efficiency expressed as compression ratio is also influenced by both the speed and feed. However, the influences of speed and feed are in opposing directions.

Tool Condition Monitoring In Micro-Milling

7790 руб.
Micro-milling is a precision milling technology where the cutting parameters are in micro scale. It has been increasingly applied to modern industry, from aerospace to bioengineering. Tool condition monitoring (TCM) in micro milling poses new challenges compared to conventional CNC machining, due to the high tool wear rate and high precision requirement associated with the features at micro-level. In this book, a generic noise-robust system is developed for the micro-milling tool condition monitoring. Mathematical tools such wavelet analysis and independent component analysis (ICA) have been applied to analyze the cutting force associated with different tool conditions. Continuous Hidden Markov models (HMMs) are adapted to model the tool wearing process and estimate the tool states based on the force features. Experimental studies on the tool state estimation in the micro-milling of pure copper and steel illustrate the effectiveness these approaches. This book serves as a valuable reference to the graduate students and the engineers engaged in the research in precision manufacturing, automation and control, and signal processing.

This work describes the optimization process for ball-end milling of sculptured surfaces such as those encountered in dies/moulds and aircraft structural components. Since cutting forces are the main factors governing machining accuracy, machine tool vibration, power requirements and tool life, a comprehensive methodology of modelling, analysis and control of cutting forces is outlined. Due to complexity and vagueness of manufacturing process, fuzzy logic controller is employed to vary cutting parameters in real-time during manufacturing process depending on the emanating cutting forces. The control scheme aims at maximizing on the material removal rate and at the same time reducing on the rate at which the tool wears out. Also the need to have a constant machine operator to supervise the machining process is elimintated.

This work experimentally demonstrated a route to synthesis of nanoporous carbide derived carbon of tunable pore size, surface area and pore volume from various binary metal carbides (boron carbide, zirconium carbide, titanium carbide, and silicon carbide). The relation between the structures of the initial metal carbide and the properties of the resultant nanoporous carbon has been studied. A systematic study on hydrogen storage capacity of carbide derived carbons and comparison with other materials including metal organic framework, single and multiwalled carbon nanotubes dispelled the popular myth that hydrogen physisorption is directly proportional to SSA, and provided guidance for optimal design by showing that a large volume of small open pores is the key to high hydrogen uptake at cryogenic temperatures and ambient pressure. Values up to 3 wt.% have been demonstrated in carbide derived carbons at 77 K and atmospheric pressure.
