Introduction




Manufacturing processes are methods or techniques used to transform raw materials into finished products. They involve various physical or chemical changes that alter the shape, size, properties or appearance of materials. Manufacturing processes can be classified into two main categories:



  • Primary manufacturing processes: These are processes that produce basic shapes or forms from raw materials, such as casting, forging, rolling, extrusion, etc.



  • Secondary manufacturing processes: These are processes that modify or improve the basic shapes or forms produced by primary processes, such as machining, welding, joining, finishing, etc.



Machining is one of the most important and widely used secondary manufacturing processes. It involves removing unwanted material from a workpiece by using a cutting tool that has a specific shape and geometry. Machining can be performed on various types of machine tools, such as lathes, drills, mills, grinders, etc.

Chapter 1: Introduction to Manufacturing Processes




This chapter introduces the concept and classification of manufacturing processes, the basic concepts and principles of manufacturing processes, and the factors affecting the selection of manufacturing processes. Some of the key points of this chapter are:



  • Manufacturing processes are methods or techniques used to transform raw materials into finished products. They involve various physical or chemical changes that alter the shape, size, properties or appearance of materials.



  • Manufacturing processes can be classified into two main categories: primary manufacturing processes and secondary manufacturing processes. Primary manufacturing processes produce basic shapes or forms from raw materials, such as casting, forging, rolling, extrusion, etc. Secondary manufacturing processes modify or improve the basic shapes or forms produced by primary processes, such as machining, welding, joining, finishing, etc.



  • The basic concepts and principles of manufacturing processes include material properties, process parameters, process variables, process capabilities, process limitations, process economics and process optimization.



  • The factors affecting the selection of manufacturing processes include product design, product quality, product quantity, product cost, production time, production flexibility and environmental impact.



Chapter 2: Metal Cutting Theory and Practice




This chapter explains the mechanics and geometry of metal cutting, the types and characteristics of cutting tools, and the cutting forces, power, temperature and tool wear in metal cutting. Some of the key points of this chapter are:



  • Metal cutting is a process of removing unwanted material from a workpiece by using a cutting tool that has a specific shape and geometry. Metal cutting can be performed on various types of machine tools, such as lathes, drills, mills, grinders, etc.



  • The mechanics and geometry of metal cutting involve the analysis of the chip formation, the shear plane angle, the rake angle, the clearance angle, the cutting speed, the feed rate and the depth of cut.



  • The types and characteristics of cutting tools include single-point tools and multi-point tools. Single-point tools have one cutting edge that performs the cutting action, such as turning tools, boring tools, shaping tools, etc. Multi-point tools have two or more cutting edges that perform the cutting action simultaneously or sequentially, such as drilling tools, milling tools, grinding tools, etc.



  • The cutting forces are the forces acting on the cutting tool and the workpiece during metal cutting. They include the tangential force (Ft), the radial force (Fr) and the axial force (Fa). The cutting forces affect the power consumption, tool life and surface finish of metal cutting.



  • The power is the rate of work done by the cutting tool on the workpiece during metal cutting. It is proportional to the product of the tangential force (Ft) and the cutting speed (Vc). The power consumption affects the energy efficiency and operating cost of metal cutting.



  • The temperature is the measure of heat generated during metal cutting. It is influenced by the cutting speed (Vc), the feed rate (f), the depth of cut (d), the tool material and geometry (rake angle), and the coolant application. The temperature affects the tool wear and material properties of metal cutting.



  • The tool wear is the gradual deterioration of the cutting edge due to friction and abrasion during metal cutting. It is measured by various parameters such as flank wear (VB), crater wear (KT), nose wear (VN), etc. The tool wear affects the tool life and surface finish of metal cutting.



Chapter 3: Machine Tools




This chapter describes the definition and classification of machine tools, the main components and functions of machine tools, and the common operations performed on machine tools. Some of the key points of this chapter are:



  • Machine tools are machines that provide controlled motion of the workpiece and the cutting tool to perform various machining operations.



  • Machine tools can be classified into three main categories: conventional machine tools, CNC machine tools, and special purpose machine tools. Conventional machine tools are manually operated or mechanically automated machines that use mechanical linkages and cams to control the motion of the workpiece and the cutting tool, such as lathes, drills, mills, shapers, etc. CNC machine tools are computer-controlled machines that use electronic devices and software to control the motion of the workpiece and the cutting tool, such as CNC lathes, CNC mills, CNC grinders, etc. Special purpose machine tools are machines that are designed for specific machining operations or products, such as gear cutting machines, broaching machines, honing machines, etc.



  • The main components and functions of machine tools include the bed, the headstock, the tailstock, the carriage, the cross slide, the compound slide, the tool post, the spindle, the chuck, the feed mechanism, the lead screw, the cutting tool, and the workpiece. The bed is the base or frame of the machine tool that supports all other components. The headstock is the part of the machine tool that houses the spindle, which is a rotating shaft that holds and drives the cutting tool or the workpiece. The tailstock is the part of the machine tool that supports the other end of the workpiece, which is usually held by a center. The carriage is the part of the machine tool that slides along the bed to provide longitudinal motion to the cutting tool or the workpiece. The cross slide is the part of the machine tool that slides on the carriage to provide crosswise motion to the cutting tool. The compound slide is the part of the machine tool that slides on the cross slide to provide angular motion to the cutting tool. The tool post is the part of the machine tool that holds and adjusts the cutting tool on the compound slide. The spindle is a rotating shaft that holds and drives the cutting tool or the workpiece. The chuck is a device that clamps and centers the workpiece on the spindle. The feed mechanism is a system of gears, levers and screws that controls the rate and direction of motion of the carriage, cross slide and compound slide. The lead screw is a long threaded rod that engages with a nut on the carriage to provide longitudinal motion to the carriage. The cutting tool is a device that has a specific shape and geometry to remove unwanted material from the workpiece by metal cutting. The workpiece is a piece of raw material that is transformed into a finished product by metal cutting.



  • The common operations performed on machine tools include turning, drilling, milling, grinding and non-traditional machining operations. Turning is an operation of producing cylindrical or conical shapes by rotating the workpiece and feeding the cutting tool along its axis. Drilling is an operation of producing holes in a workpiece by rotating and feeding a multi-point cutting tool into it. Milling is an operation of producing flat or curved surfaces by rotating and feeding a multi-point cutting tool across a stationary workpiece. Grinding is an operation of producing smooth and accurate surfaces by rotating and feeding an abrasive wheel against a workpiece. Non-traditional machining operations are operations that use physical or chemical phenomena other than metal cutting to remove material from a workpiece, such as electric discharge machining (EDM), laser beam machining (LBM), ultrasonic machining (USM), etc.



Chapter 4: Turning Operations




This chapter discusses the definition and classification of turning operations, the parameters and methods of turning operations, and the types and applications of turning operations. Some of the key points of this chapter are:



  • Turning operations are operations of producing cylindrical or conical shapes by rotating the workpiece and feeding the cutting tool along its axis.



  • Turning operations can be classified into two main categories: straight turning and taper turning. Straight turning is an operation of producing a cylindrical shape by feeding the cutting tool parallel to the axis of rotation. Taper turning is an operation of producing a conical shape by feeding the cutting tool at an angle to the axis of rotation.



  • The parameters of turning operations include the cutting speed (Vc), the feed rate (f), the depth of cut (d), and the surface finish (Ra). The cutting speed (Vc) is the linear speed at which the workpiece rotates. The feed rate (f) is the linear distance traveled by the cutting tool per revolution of the workpiece. The depth of cut (d) is the radial distance between the uncut surface and the cut surface. The surface finish (Ra) is the arithmetic average deviation from the mean surface.

  • The parameters of milling operations include the cutting speed (Vc), the feed rate (f), the depth of cut (d), the surface finish (Ra), and the surface accuracy (IT). The cutting speed (Vc) is the linear speed at which the milling cutter rotates. The feed rate (f) is the linear distance traveled by the workpiece per revolution of the milling cutter. The depth of cut (d) is the axial distance between the uncut surface and the cut surface. The surface finish (Ra) is the arithmetic average deviation from the mean surface. The surface accuracy (IT) is the tolerance grade that specifies the allowable deviation from the nominal size.



  • The methods of milling operations include conventional milling, climb milling, up milling, down milling, slab milling, end milling, face milling, side milling, form milling, profile milling, pocket milling, contour milling and gear milling. Conventional milling is a method of producing flat or curved surfaces by feeding the workpiece against the direction of rotation of the milling cutter.

Up milling is a type of conventional milling in which the workpiece is fed from low to high along the axis of rotation of the milling cutter. Down milling is a type of climb milling in which the workpiece is fed from high to low along the axis of rotation of the milling cutter. Slab milling is a type of peripheral milling in which the workpiece is fed past a wide and flat milling cutter. End milling is a type of peripheral milling in which the workpiece is fed past a narrow and cylindrical milling cutter. Face milling is a type of face milling in which the workpiece is fed past a wide and flat milling cutter. Side milling is a type of face milling in which the workpiece is fed past a narrow and cylindrical milling cutter. Form milling is a type of peripheral or face milling in which the workpiece is fed past a specially shaped or profiled milling cutter. Profile milling is a type of peripheral or face milling in which the workpiece is fed along a predetermined path or contour by using a tracer or a computer program. Pocket milling is a type of peripheral or face milling in which a cavity or recess is produced on a workpiece by using an end mill or a ball mill. Contour milling is a type of peripheral or face milling in which a curved or irregular shape is produced on a workpiece by using an end mill or a ball mill.

It is used for making angles, bevels, chamfers, etc. Straddle milling is a type of milling operation that produces two parallel flat surfaces on opposite sides of a workpiece by using two side milling cutters mounted on the same arbor. It is used for making keys, slots, grooves, etc. Gang milling is a type of milling operation that produces two or more flat or curved surfaces simultaneously by using two or more milling cutters mounted on the same arbor. It is used for making patterns, arrays, grids, etc. String milling is a type of milling operation that produces a series of flat or curved surfaces along the length of a workpiece by using a single long and flexible milling cutter. It is used for making helical gears, worms, threads, etc. Index milling is a type of milling operation that produces a series of flat or curved surfaces at equal angular intervals around the circumference of a workpiece by using an index head or a dividing head. It is used for making gears, splines, cams, etc.
