It involves preparing the material using appropriate method- setting up forging machines with dies and presses and using forging techniques so that the material forms the shape as per the die. It also involves checking the prepared components for accuracy.
It involves selecting appropriate grinding equipment- tools and methods to suit work requirements- preparing the tools- applying grinding procedures for carrying out the grinding operations- inspecting the components after grinding operations and correcting faults.
It involves applying pre-heat treatment procedures- carrying out heat treatments such as flame hardening- case hardening- hardening- carburizing- tempering- annealing and normalizing- as applicable. It also involves inspecting the components and correcting faults.
It involves identifying and using relevant methods and skills to complete the testing and address problems. It involves initiating and completing testing and procedures using a range of different metal testing methods and equipments used within the workplace.
It involves preparing the products for testing, identifying the test area, checking that the radiographic test equipment complies with the specification requirements, is safe to use, fit for purpose. It also involves adjusting the radiographic equipment, choice of suitable technique for the product, carrying out the exposure, ensuring safe containment of the radiography source, process the exposed films in the prepared facility, checking the image quality before storing the film ready for interpretation.

Machinist General operates various types of power driven metal cutting or grinding machines for cutting and grinding metal. Studies drawings or measures out sample with appropriate measuring instruments to note different dimensions and sequence of operations required. Selects metal piece and marks it or gets it marked for machining operations required. Fastens metal in chuck, jig or other fixture and respective tool or cutter, according to sequence of operation, on appropriate machine (lathe, shaper, milling, slotting, drilling, grinding). Checks machine setting or sets it for stipulated machine operations. Selects machine feed and speed and starts machine. Controls flow of coolant (cutting lubricant) and manipulates hand wheels or applies automatic controls to feed tool to metal or metal to tool. Observes cutting or grinding both from marking and machine readings, checks for dimensions as necessary and removes parts when machining is completed, checks completed part with measuring instruments and gauges to ensure prescribed accuracy. Makes adjustments if necessary and repeats operations, as required, on same or other machines. May assist in setting up machine for repetitive work, change tools, make simple adjustments, clean and oil machine. Demonstrate the operation of CNC Machining Center (3-axes) and producing components as per drawing by preparing part programmes. Plan and organize assigned work and detect & resolve issues during execution. Demonstrate possible solutions and agree tasks within the team. Communicate with required clarity and understand technical English. Sensitive to environment, self-learning and productivity.
Grinder, grinds machine tools and cutter to correct specifications by special grinding machines and wheel. Studies drawings and other specifications to understand nature of grinding operation required. Fastens appropriate abrasive wheel to spindle of machine. Mounts cutting tool to be ground on machine using dividing head, jig or fixture as required. Manipulates swivel tables, wheel head and work holding device, guide finger, etc. as necessary to set machine to appropriate angle for grinding desired level on cutting edges of tool selects and sets speed and feed to machine according to nature of work and wheel used. Starts machine, brings rotating grinding wheel in contact with edge of tool and grinds proper angles, clearance, flutes etc. as required on tool or cutter set, frequently checking it with gauge or measuring instrument while grinding to ensure accuracy. Rotates work through proper angle by dividing head or otherwise to set next flute or teeth of tool or cutter for grinding and continues operation. Uses cutting fluid or coolant as found necessary and ensures that no part of work gets burnt or damaged while grinding. Stops machine and removes tool when grinding is completed. Changes grinding wheel and position of tool as and when required. May give final finish to cutting edge by hand using hones. May oil and clean machine. May specialize in grinding a particular type of tool and be designated accordingly. May check ground tool or cutter by shadow projector to ensure accurate finish. Grinder Operator makes metal articles to required specifications using lathe and cutting tools. Studies drawings and other specifications of parts to be made. Selects metal, holds it in chuck, jig or fixture on lathe as required, centres it by manipulating chuck jaws or otherwise using dial indicator or marking block and securely tightens it in position. Selects correct cutting tool, grinds it if necessary and holds it tight in tool post at correct height. Sets feed and speed and starts machine. Manipulates hand wheels or starts automatic controls to guide cutting tool into or along metal. Controls flow of coolant (cutting lubricant) on edge of tool. Arranges gears in machine to obtain required pitch for screw cutting. Calculates tapers and sets machine for taper turning, controls lathe during operation by means of hand wheels and levers and frequently checks progress of cutting with measuring instruments such as calipers and rule, micrometers, etc. Stops machine, removes completed part and checks it further with instruments to ensure accuracy.
This will involve dismantling- removing and replacing faulty equipment at component or unit level on a variety of different types of mechanical assemblies and sub-assemblies and diagnosing- locating faults- overhauling- fitting and adjusting mechanical systems and equipment.
Perform these above mentioned operations as per WPS(Welding Procedure specification). and can set-up and prepare for operations interpreting the right information from the WPS- obtaining the right consumables and raw materials- etc. and the candidate must know how to use the same in a safe manner following practices that ensure safety for self- others and the work environment and and assess weld quality through visual inspection.
