Tooling_U Chapter 6 Questions Flashcards
define single point and multipoint tooling
Single-point tooling and multipoint tooling are two distinct types of cutting tools used in machining and manufacturing processes. They differ in the number of cutting edges or points they have and their respective applications:
Single-Point Tooling:
Definition: Single-point tooling, as the name suggests, has only one cutting edge or point that comes into contact with the workpiece. These tools are typically used in turning, boring, and facing operations.
Applications: Single-point tools are commonly employed in processes like turning on a lathe, where the tool bit is shaped to have a single sharp cutting edge. They are also used for tasks like shaping and contouring, where precision and control are essential. Single-point tools are versatile and suitable for creating complex geometries with high precision.
Multipoint Tooling:
Definition: Multipoint tooling, on the other hand, consists of cutting tools with multiple cutting edges or points distributed across the tool’s surface. These tools are often referred to as milling cutters, drills, or end mills.
Applications: Multipoint tools are used in milling, drilling, and other operations where material removal occurs primarily through the coordinated action of multiple cutting edges. For example, milling cutters have several teeth or inserts that engage the workpiece simultaneously, making them efficient for removing larger volumes of material and creating flat or contoured surfaces. Drills have multiple cutting edges along their flutes for creating holes.
Define Machining
Machining is a manufacturing process that involves the removal of material from a workpiece to create a desired shape, dimension, or surface finish. This material removal is achieved through various cutting, shaping, and finishing operations using specialized tools and machinery. Machining processes are widely used in industries such as manufacturing, aerospace, automotive, and precision engineering to produce parts and components with high accuracy and precision.
Key characteristics of machining include:
Material Removal: Machining involves the precise removal of material from a workpiece, often in the form of chips or swarf. This process is the opposite of additive manufacturing, where material is added to build a part.
Tooling: Specialized cutting tools, such as drills, milling cutters, turning tools, and grinding wheels, are used to cut, shape, or finish the workpiece.
High Precision: Machining processes are known for their ability to achieve tight tolerances and high levels of accuracy, making them suitable for applications where precision is critical.
Versatility: Various machining techniques, including milling, turning, grinding, drilling, and electrical discharge machining (EDM), are available to address a wide range of manufacturing needs.
Surface Finish: Machining can be used to improve the surface finish of workpieces, resulting in smoother, more precise surfaces.

Describe Sawing
Sawing is a material removal process used to cut or separate materials, typically in the form of solid workpieces, into desired shapes or sizes. This process is characterized by the use of saw blades, which have teeth or abrasive edges that remove material as they pass through the workpiece. Sawing is a versatile and widely used machining method that can be applied to various materials, including metals, wood, plastics, and composites. It is commonly used in construction, woodworking, metalworking, and manufacturing industries for a wide range of applications.

Regular maintenance of saw blades is essential to ensure efficient cutting and prolong the life of the tools. This may include sharpening, cleaning, and replacing blades as needed.
distinguish between the three main categories of cutting operation
Cutting operations in machining can be broadly categorized into three main categories based on the type of tooling and the process characteristics. These categories are turning, milling, and drilling. Here’s a distinction between these three main categories of cutting operations:
Turning:
Tool Type: In turning operations, a single-point cutting tool is used. This tool has a single cutting edge or point that comes into contact with the rotating workpiece.
Process: Turning involves the rotation of the workpiece while the cutting tool is held stationary. The cutting tool removes material from the workpiece to create cylindrical shapes, such as shafts, rods, and cones.
Applications: Turning is commonly used for tasks like creating cylindrical or conical shapes, grooves, threads, and facing operations. It is ideal for producing rotational symmetry.
Milling:
Tool Type: Milling operations employ multipoint cutting tools known as milling cutters. These cutters have multiple teeth or inserts distributed around their periphery.
Process: Milling involves the rotation of the milling cutter while the workpiece is typically held stationary. Material is removed as the cutter’s teeth engage the workpiece simultaneously, producing flat or contoured surfaces.
Applications: Milling is versatile and can be used for tasks such as creating flat surfaces, slots, pockets, gears, threads, and complex 3D shapes. It is suitable for producing various shapes and profiles.
Drilling:
Tool Type: Drilling operations utilize specialized cutting tools known as drills. Drills have one or more cutting edges along their length for creating holes.
Process: In drilling, the drill bit rotates and is advanced into the workpiece to create holes. The material is removed as the drill’s cutting edges shear through the workpiece.
Applications: Drilling is primarily used for creating holes of various sizes and depths in a workpiece. It is a fundamental operation for many applications in construction, manufacturing, and fabrication.
Describe common cutting processes performed on a lathe
Lathes are versatile machine tools used in machining operations to create cylindrical, conical, and contoured parts by rotating a workpiece and using single-point cutting tools. Here are some common cutting processes performed on a lathe:
