Bharani Hydraulics pvt ltd, Tamil Nadu, India: (1 month)
Worked as a programming apprentice for engineering projects with a team of 4 people Automated vertical storage carousal for storing parts in the inventory
Design (Auto CAD) and fabricated 16 racks of storage bins with vertical reach of 9 feet and width of 4 feet
Have hands on experience working with stepper motor interfaced with rotary encoders
Researched relevant sensors and motors based on requirements for the project and prepared purchase order quotations
Programmed a hydraulic press with electrically actuated solenoid valves (Directional control valves) for hydraulic circuit
Worked on interfacing mechanical limit switches on the hydraulic press and programmed the Siemens PLC using CX-one ladder logic program
Limit switches are hardwired with PLC for program inputs and monitored the hydraulic circuit design and layout for the hydraulic press
