BTEB Machinist study plan

Define the four exam domains and write a one-page map linking each to the workshop activities you already perform

List the common workshop hazards (rotating parts, swarf, hot chips, lifting, electrical) and state one control measure for each

Identify and label the main hand tools and measuring instruments used in bench work from memory, without notes

Demonstrate correct use of a steel rule, try square and vernier caliper on three sample workpieces and record each reading

Explain the purpose of machine guards, emergency stops and lockout procedures in three written sentences each

Describe first-aid and fire-response steps for a metal-cutting workshop, including the correct extinguisher class for oil and electrical fires

Practise safe filing, hacksawing and chiselling technique on a scrap mild-steel block, checking stance and stroke

Measure five marked dimensions on your practice block and tabulate nominal versus actual values

Define datum, reference surface and tolerance, and apply each term correctly when describing a marked-out workpiece

Perform marking-out of a rectangular plate using surface plate, scriber, height gauge and dividers to within 0.2 mm

Explain the difference between clearance, interference and transition fits and match three standard examples to each type

Calculate allowance and tolerance for two given shaft-and-hole pairs and state whether each is a clearance or interference fit

Read a vernier caliper, micrometer and dial indicator to their stated resolution and record ten readings with zero error applied

Describe the main parts of a centre lathe (headstock, tailstock, carriage, leadscrew, feed gearbox) and state the function of each

Explain the purpose of cutting speed, feed rate and depth of cut, and calculate spindle speed for two given material-and-tool combinations

Set up a workpiece in a three-jaw chuck and check run-out with a dial indicator

Perform plain turning and facing on a mild-steel bar to a specified diameter and length within 0.1 mm

Grind or set a turning tool to the correct rake and relief angles and explain why each angle matters

Describe the procedure for drilling and reaming on the lathe using the tailstock, including alignment checks

List the causes and corrections for four common lathe faults: chatter, taper, poor finish and tool wear

Explain thread terminology (pitch, lead, major and minor diameter) and cut an external thread on the lathe or by die to a given specification

Describe the safe setup and operation of a drilling machine and a milling machine, naming the guards and clamps used

Outline a preventive maintenance schedule for a lathe, listing lubrication points, belt checks and alignment checks with intervals

Interpret a simple assembly or part drawing and extract the dimensions, tolerances and surface-finish notes needed to machine it

Compare the properties and typical uses of mild steel, high-carbon steel, cast iron, aluminium and brass in a written table

Explain heat-treatment processes (annealing, normalising, hardening, tempering) and state the effect of each on hardness and toughness

Describe the correct selection and application of cutting fluids for turning, drilling and grinding

Identify five common causes of tool wear or failure and state the corrective action for each

Review all four domains using a self-made summary sheet of key formulas, tolerances and safety rules

Complete two full-length timed practice sets under exam conditions and score each against the answer key

Analyse every missed question, classify the error as knowledge gap, misreading or calculation slip, and re-study the weakest two areas

Re-demonstrate the three measurement and machining skills you scored lowest on and confirm they now meet tolerance
