    Title: 

    "A Fundamental Study in Machinability of some Engineering Materials", Faculty of Engineering & Technology, Suez Canal University, Egypt, 1983.

     

    Summary:

    The study presents a comparative approach to evaluate the machinability of three categories of engineering materials: free-machining brass, aluminum, and medium carbon steel. Machinability was handled through some new indices of chip curling and breaking.

    Experimental testing was carried out for both orthogonal and oblique states with and without lubricant using high speed steel turning tools. Wide ranges of  each of the cutting parameters, speed-feed-depth of cut, were applied and investigated functionally.

    Two chip curling based machinability indices were introduced. One considering the conventional chip ratio and the other was the curing ration denoted as the ratio of the initial to the fractured chip curling radius.

    Furthermore, chip breaking based machinability investigation was carried out experimentally through two breaker designs namely; obstruction and groove types.

    Breakability factor was proposed as the volumetric ratio of chip with and without breakers.

     

     

     

    Title: 

    "Mathematical Modelling and In Process Monitoring Techniques for Cutting Tools", University of Sheffield, 1989.

     

    Summary:

    The need is expressed for mathematical models which describe the cutting-workpiece-machine tools interaction and for accurate on-line monitoring of tool state and its performance criterion measure.

    Study comprises of two main phases: experimental procedures including design of the test rig and carrying out tests, and empirical formulation of the obtained results.

    In the experimental part of the study, multi coated indexable carbide turning inserts are used to cut hardened and tempered ally steel under wide variety of practical operating parameters. Measurements include tool wear scars on three different sites of the cutting edge along with the corresponding of  three static cutting forces components and vibration components.

    In the second phase of the work, linear and non-linear conventional regression analysis are applied to develop mathematical models for the experimentally measures responses. Also, power spectral analysis is used to analyze the tool vibration under different wear states (tool life).

    Different in-process monitoring models are developed considering the mutual relationships and interaction between tool wear; tool life; force components and cutting vibration. many findings are presented to justify the implementation of the approach.

    At the end of the work, it was advised to go on with the topic bearing in mind the possible practical application in CNC and AC systems considering the enhancement provided by new technology.

    In fact, this was the center of my post research work in the subsequent fifteen years.
