Simple material topology

Types of materials

Material types

Materials used in manufacturing can be divided into the following categories:

• Metals – examples of metallic material are iron (Fe) and copper (Cu)
• Non-metals – e.g. carbon (C), silicon (Si)

Iron makes another division:

• Ferrous metals – the ones containing iron
• Non-ferrous metals – the ones without iron

Elements, compounds and mixtures

When it comes to the chemical composition, the materials are divided into:

1. Elements – the materials in their very basic form. They are not broken into other constituencies/ingredients. Elements widely used in engineering are e.g. iron, carbon, aluminum
2. Compounds – include 2 or more elements that have chemical bonds – that is they are combined by chemical reaction, e.g. sodium chloride (NaCl), we use it every day.
3. Mixtures – include 2 or more elements or compounds mixed together. However, they are not chemically bound. In manufacturing sector, common examples are alloys – metals that consist of other metals and/or non-metals mixed with them. The most common example would be iron-carbon alloy, and can include other alloying metals – metals which are added to alloys in small quantities, e.g. chromium (Cr), tungsten (W)

Composites

A composite is a combination of two or more chemically distinct materials whose physical characteristics are superior to its constituents acting independently.

Examples of composites include:

1. Reinforced Plastics
2. Ceramic-matrix
3. Metal-Matrix
4. Laminates

Further materials include:

1. Ceramics
2. Wood
3. Plastics
4. Gases
5. Liquids

4. Location of the fuel takns

Different CNC techniques

CNC Machining:

Machining is the process of using machines to cut workpieces and to shape them to the desired size and shape. Holes, grooves, threads are the results of the machining. By-products being resulted from the machining are swarves or chips. Very often during the machining, an excessive amount of heat is produced. That is why the process requires the usage of coolant. There are 2 types of machining: conventional and CNC – Computerized Numerical Control. The latter is often reinforced by two types of software: CAD – Computer-Aided Design and CAM – Computer-Aided Manufacturing

Most common machining procedures are:

1. Milling – cutting by a milling machine, often used disc cutting devices equipped with teeth
2. Turning – is a technique for cutting components that have circular cross-sections
3. Sawing – is cutting using the blade with teeth. The gap left by the blade, along the line of cut is called a kerf. We may identify the following types of saws: circular saw, band saw, power hacksaw, holesaw – hollow cylinder with teeth (used for drilling, see no. 4)
4. Drilling – a technique for cutting circular holes. The machine uses drill bits (or bits). Enlarging the existing hole is called boring. Core drilling or diamond drilling is used when we drill into concrete
5. Grinding – used when an excessive material is required to be removed
6. Shot-peening – is a cold work process used to finish metal parts to prevent fatigue and stress corrosion failures and prolong product life for the part. In shot peening, a small spherical shot bombards the surface of the part to be finished
7. Broaching – is a machining process that uses a toothed tool, called a broach, to remove material. There are two main types of broaching: linear and rotary

Language education of future technician and engineers

The concept of educating future aviation mechanics, both structural and engine repair specialists, includes, apart from technical aspects, education in specialist English. Employees of the company with the MRO profile must correctly and properly recognize the instruction on the job cards and in the AMMs so that there is no mistake, which may end tragically. The most important linguistic elements of their education are:

1. Imperative
2. principal tenses – present simple / continuous, past simple, present perfect
3. Passive voice
4. Prepositions, pronouns and particles
5. Modal verbs and their functions
6. Vocabulary in the field of among others:

• types of materials used in aviation and their properties
• flight theory,
• aircraft structural components and their functions,
• engine structure and function of its components,
• engine disassembly and assembly,
• quality inspection and testing procedures, including non-destructive testing (NDTs),
• engine parts cleaning and maintenance procedures,
• types of damage and types of foreign materials,
• human factor
• abbreviations

Please find below some ideas for exercises

• Find synonyms and opposites:

• to disassemble =
• to contain =
• rear =
• front =
• to perform =
• to adjust =
• to speed up
• to retract ≠
• to refuel ≠
• to push ≠
• to connect ≠
• to inflate ≠

• Complete the following sentences:

• The fuselage consists of……………………………………………………………………………..
• The empenage consists of………………………………………………………………………….
• The stringers are………………………………………………………………………………………..
• Elevator controls………………………………………………………………………………………..
• Landing gear is located……………………………………………………………………………..
• Flaps are located on…………………………………………………………………………………..
• Slats are located on…………………………………………………………………………………..
