It involves carrying out CNC grinding operations in line with safe working practices and approved procedures- to continuously monitor the machining operations and- where necessary- make minor adjustments or seek the help of the setter to make the required adjustments- in order to ensure that the work output is to the required quality and accuracy.
It involves removal of metal from the outer diameter of a rotating cylindrical workpiece. It also involves inspecting the components and continuously monitoring of the machining operations and making minor adjustments in order to ensure that the work output is to the required quality and accuracy.
It involves producing components that combine a number of different features, such as flat faces, parallel faces, faces square to each other, faces at an angle, steps/shoulders, open and enclosed slots, drilled, bored and reamed holes, internal threads, and special forms. It involves continuously monitoring, inspecting the components and meeting production targets.
Produce the component program using manual data input or by use of a remote computer- saving the prepared program on the machine controller from the computer. This involves understanding the CNC machine tools used in the process- their application and programming- editing and proving process- in adequate depth to provide a sound basis for carrying out the activities.
It involves setting up the CNC turning machine- its work holding devices- tooling- loading the machine operating programmes- conducting trial runs and correcting faults- in order to ensure that the work output is produced as per specification.
It involves setting up cutting tools and workholding devices for producing components that combine a number of different features- conducting trial runs- proving the program tool by tool in single block mode- performing the necessary checks before allowing the machine to operate in full program run mode and then handing over for production.
A trainee attending the course on ‘CO2 welder’ shall be able to read fabrication drawing, examine, clean and clamp parts to be welded. The trainee shall be able to connect work piece with earth cable, welding machine with suitable gas cylinder, regulator, flow meter, and pre-heater when CO2 is used as shielding gas. The trainee shall be able to select suitable wire electrode, feed it to welding CO2 Welding torch through wire feeder, select contact tip gas nozzle and fit into the CO2 welding torch, preheat joints, start the Constant Voltage CO2 welding machine, set suitable welding voltage & wire feed speed and shielding gas flow, produce arc between work piece and continuously fed wire electrode. The trainee also melts the metal and deposit weld beads on the surface of metals or joins metal pieces such as carbon steels, and low alloy steels to a required quality, minimizing distortion and avoiding weld defects.
