INDUSTRIAL EXPERIENCE

1995 - 1999  Research and Development Engineer ALLIED MACHINE & ENGINEERING Corp, Dover, Ohio
    Established a machining experimentation Laboratory for product (spade drills) testing and evaluation. Successful studies were performed on optimizing the cutting action of drilling performance. Results are proprietary material of AMEC. Briefly, the Lab utilizes the following Techniques:

    • Vibrations and chatter testing; Accelerometers (piezoelectric and strain gage types) for vibration monitoring and testing.
    • Cutting forces measurements; Strain gage bridges for measuring loads and stresses in addition to Piezoelectric rotary dynamometer.
    • Acoustic emission signals for tool condition monitoring.
    • Computerized Data Acquisition system:


    In addition to the experimental investigation of tool life and chip formation, I used the finite element analysis (FEA) technique to perform stress and modal analysis studies on fixtures and tool holders. Also, I worked on modeling chip formation using a commercial FEA package.
1993 - 1995  Project Manager Cleveland Trencher Company, Cleveland, Ohio
  • Worked on projects for the design and fabrication of heavy duty trenching machines. Provided Engineering Estimates and Cost Studies. Reviewed bids for special trenchers

  • Designed a hydrostatic crawler drive system to replace the mechanical crawler drive on the model 400W-HD trencher. Designed the control console for the 400W
  • Designed Engine doors and chain guards for the models 7036-SD and 7648 trenchers
  • Reviewed and translated technical contracts and machines charts (Arabic-English).
  • Designed a new gravel hopper for the model 246-FD farm drainage trencher
  • Designed a complete chain boom attachment to replace the digging wheel on the Model 9600-S trencher
  • Worked on engineering application projects for machine maintenance, machine modifications and other customer technical services.
