A drilling machine operation is the process of creating, enlarging, or finishing holes in a workpiece using a rotating cutting tool called a drill bit. The machine works by rotating the drill bit at high speed while applying downward pressure to cut into the material. Common operations performed include drilling, reaming, counterboring, countersinking, tapping, and spot facing. Drilling machines are widely used in metalworking, woodworking, and construction due to their accuracy, efficiency, and ability to produce holes of different sizes and depths.

Fisheries and aquaculture. It is intended to the learners pursuing TVET Certificate

V in Animal health. Upon completion of this module the learners will be able to

Install aquaculture system, assist in hatching operations, perform nursery

activities, grow and harvest fishes.

This module covers the knowledge; skills and attitudes required to provide a balanced feeding to domestic animals by managing fodder crops and pasture in an optimum manner. It is intended for learners who have successfully completed ordinary level, level II in animal health or its equivalent and pursuing TVET level III and related qualification. Upon completion of this module, the trainee will be able to: Cultivate fodder crops, perform pastures lay out and improvement and Manage pasture grazing

This module describes the skills, knowledge and attitudes required to identify history of food processing industry, identify food safety requirements and describe important processing operations in the food industry. At the end of this module, participants will be able to identify most important historical events of the transformation of cooked ingredients, by physical or chemical means into food, or of food into other forms. Learners will be able to improve food safety-related behaviours and practices. They can describe food processing activities such as mincing and macerating, liquefaction, emulsification, and cooking, pickling, pasteurization, and many other kinds of preservation and canning or other packaging.

Forging is a manufacturing process in which metal is shaped into the desired form by applying compressive forces using hammers, presses, or dies. The process is usually carried out at high temperatures (hot forging), but it can also be done at room temperature (cold forging). Forging improves the strength, toughness, and grain structure of the metal, making it suitable for producing strong and durable components like shafts, gears, bolts, and tools.

Forging is a metalworking process where compressive forces are applied to shape metal, typically using a hammer or press. It improves mechanical properties by aligning the grain structure.

🔹 Purpose:

• To produce strong, durable parts
• Used in high-stress applications (e.g., automotive, aerospace, tools)

🔹 Types of Forging:

1. Open-Die Forging
• Workpiece is compressed between flat dies
• Suitable for large or simple shapes
2. Closed-Die Forging (Impression Die)
• Metal is compressed in a die cavity
• High precision and complex shapes
3. Cold Forging
• Performed at room temperature
• Better surface finish, high dimensional accuracy
4. Hot Forging
• Done above recrystallization temperature
• Easier to shape, less stress on equipment

🔹 Materials Used:

• Steel (carbon, alloy, stainless)
• Aluminum
• Titanium
• Brass and copper
