4.1 Identify the lathe component in FIGURE 4.1 below - NSC Mechanical Technology Fitting and Machining - Question 4 - 2022 - Paper 1

The screw-cutting dial gauge on a lathe machine serves to assist the operator in engaging a lead screw by allowing accurate positioning during machining.

A standard DRO system on a lathe machine typically displays 2 axes, which are the longitudinal and transverse movements.

CNC milling machines primarily utilize G-codes for programming the movement of machine tools.

The size of the carbide ball used in a Brinell hardness tester is typically 10 mm.

The precision measuring tool shown in FIGURE 4.6 is an Outside micrometer, used for measuring external dimensions with high accuracy.

When lifting a load, the type of stress caused in a cable of a hoisting crane is known as Tensile stress.

The value of the safety factor is primarily determined by The consequences of failure, emphasizing safety in design.

An example of PVC (Polyvinyl Chloride) is Cling wrap, which is commonly used for packaging and preservation.

An advantage of nylon is that it Can quickly turn to liquid, making it useful for applications that require melting or molding.

A in FIGURE 4.11 refers to the Root of the screw thread, which is the deepest point of the thread profile.

An advantage of a multiple-start screw thread is that it Produces faster movement, allowing quicker adjustments.

A block and tackle system is commonly referred to as a pulley system, used for lifting heavy loads.

The symbol of the hydraulic component in FIGURE 4.14 represents a Pump, which is essential for hydraulic systems.
