Engineering Design Department

  • Wear prediction for dry revolute joint with clearance in multibody system by integrating dynamics model and wear model
    • The objective of this task was to study the wear phenomenon of dry revolute clearance joints in multibody systems based on the Archard’s wear model computational methodology.
  • Force analysis of a JCB Hand Control Lever
    • The task was to provide a theoretical model to account for the force required to rotate the JCB Hand Control Lever.
    • The amount of force required to rotate the lever finds its direct dependence on the amount of compression of the wave spring.

Manufacturing and Production Department

  • Product Assembly Process Control
    • Implemented image processing using OpenCV libraries and Raspberry Pi hardware to detect flaws during part assembly to significantly reduce part rejection percentage on the production line.
    • Application of canny edge detection and brute-force matching techniques on RaspberryPi using OpenCV Libraries to obtain the orientation of the magnet installed into the pedal to ensure correct North-South pole fixture to guarantee proper programming of the magnet rotation dependent sensor.
    • Implemented image thresholding and colour detection using OpenCV Libraries to ensure the application of grease on the hand control lever hub surface during its assembly on the production line.

      The proposed project is one of a kind that was aimed at replacing the costly setup with a cheaper yet reliable hardware which received great appreciation from the company.

  • Acquired knowledge on PFMEA (Process Failure Mode and Effect Analysis), inventory management, maintaining employee skill matrix, daily production yield and delivery accuracy.

Quality Engineering Department

  • Involved in the study of 7 QC Tools, 8D Method for problem solving, MSA (Measurement System Analysis), SPC (Statistical Process Controls) for assembly process optimisation.
  • Investigated the technical specifications and engineering design procedure by studying the drawing standards, dimensioning and tolerancing followed during New Product Design.
  • Analysed the tolerance values of the parts , identified inefficiencies and suggested corrective action.
  • Conducted lever break test, spring fatigue and force test and worked on CMM (Coordinate Measuring Machine) to inspect dimensional accuracy of the job before approving the part for production.

Supply Chain Management Department

  • Carried out careful inspection of PPAP (Production Part Approval Process) to generate Bill of Material (BOM) for a product to maximise production effectiveness.
  • Coordinated with the CSR Department on processing orders, handling customer complaints, customer scheduling to ensure on-time delivery (OTD) to the customers, supplier selection procedure (SSP), purchase requisition and raw material import procedure.
