Broaching is a metalworking process that involves removing material from a workpiece using a specialized cutting tool called a broach. The broach consists of a series of teeth that progressively increase in size, allowing it to remove material in a single pass. Broaching is often used to create precise internal features such as keyways or splines in metal parts. It requires specialized equipment and skilled operators to ensure accurate, efficient production.

Chamfer is a skill used in various industries such as architecture, carpentry, metalworking, and engineering. It involves cutting or grinding down the edges of a material to create a bevel, usually at a 45-degree angle. This technique is used to strengthen the material, prevent it from chipping, and create a more polished look. Chamfering is often used in woodworking to create a smooth edge or to create a stronger joint between two pieces of wood.

Jig Borer refers to a precision machining process that involves the use of a jig borer machine to create accurate holes and features in workpieces. This skill encompasses the ability to set up and operate the machine, ensuring precise alignment and measurement for intricate components. Knowledge of Jig Borer is utilized in manufacturing and engineering to achieve high levels of accuracy in the production of parts that require tight tolerances and complex geometries. The skill is essential for tasks such as tooling, fixture design, and the fabrication of components in various industries.

Numerical Controls refer to the automated systems that manage machine tools through programmed commands, enabling precise control of machining processes. This skill encompasses the understanding of programming languages and control systems that dictate the movement and operation of machinery. Knowledge of Numerical Controls is used to enhance manufacturing efficiency, improve product accuracy, and facilitate complex machining tasks by enabling the automation of repetitive processes.

Speeds and feeds refer to the parameters used to determine the optimal cutting parameters for machining operations such as milling, drilling, and turning. This requires a specialized skill as it involves an understanding of various factors such as the material being machined, the cutting tool's geometry, and the machine's capabilities. Effective use of speeds and feeds can result in improved efficiency, reduced wear and tear on equipment, and better quality parts.
