Types of Metal Cutting Machine Tools
Metal cutting machine tools can be classified according to various criteria, such as process type, geometry type or motion type. Here are some common classifications:
Process type: Metal cutting machine tools can be divided into two main categories: conventional machining processes and non-conventional machining processes. Conventional machining processes use a sharp cutting tool to remove material from a workpiece by mechanical action. Examples include turning, milling, drilling, grinding, etc. Non-conventional machining processes use other forms of energy to remove material from a workpiece without direct contact between the tool and the workpiece. Examples include laser, ultrasonic, electrochemical, etc.
Geometry type: Metal cutting machine tools can be classified according to the shape of the cutting tool or the workpiece. For example, single point tools have one cutting edge and are used for turning, boring, planing, etc. Multiple point tools have more than one cutting edge and are used for milling, drilling, broaching, etc. Circular tools have a circular shape and are used for turning, milling, grinding, etc. Prismatic tools have a prismatic shape and are used for planing, shaping, broaching, etc.
Motion type: Metal cutting machine tools can be classified according to the relative motion between the tool and the workpiece. For example, rotary motion means that the tool or the workpiece rotates around an axis. Translatory motion means that the tool or the workpiece moves in a straight line. Intermittent motion means that the tool or the workpiece moves periodically or discontinuously.
Different types of metal cutting machine tools have different features and applications. For example, turning machines use a single point tool to produce cylindrical or conical surfaces on a rotating workpiece. Milling machines use a multiple point tool to produce flat or curved surfaces on a moving workpiece. Drilling machines use a multiple point tool to produce holes on a fixed workpiece. Grinding machines use a circular tool to produce smooth and accurate surfaces on a rotating workpiece.
Fundamentals of Metal Cutting and Machine Tools
Metal cutting and machine tools involve complex physical phenomena that require a solid understanding of the fundamentals of metal cutting processes. Some of the important topics in this area are:
Basic principles and mechanics of metal cutting processes: This topic covers the basic mechanism of chip formation in metal cutting, the velocity diagram in the cutting zone, the shear angle and the rake angle of the cutting tool, the types of chips and chip breakers, etc.
Factors influencing metal cutting performance: This topic covers the factors that affect the quality and efficiency of metal cutting processes, such as cutting speed, feed, depth of cut, tool angles, cutting fluids, etc. These factors influence the cutting forces, power, temperature rise, tool life, type of chip, surface finish, etc.
Cutting tool materials, wear mechanisms and tool life: This topic covers the properties and selection of cutting tool materials, such as high speed steel, carbide, ceramic, etc. It also covers the wear mechanisms and wear patterns of cutting tools, such as flank wear, crater wear, chipping, etc. It also covers the methods to measure and predict tool life and tool wear.
Surface finish and surface integrity of machined parts: This topic covers the factors that affect the surface finish and surface integrity of machined parts, such as roughness, hardness, residual stress, microstructure, etc. It also covers the methods to measure and improve surface finish and surface integrity.
Machining economics and optimization: This topic covers the economic aspects of metal cutting processes, such as cost analysis, productivity analysis, break-even analysis, etc. It also covers the methods to optimize metal cutting processes, such as design of experiments, response surface methodology, genetic algorithms, etc.
Modern Developments in Metal Cutting and Machine Tools
Metal cutting and machine tools are constantly evolving with the advancement of science and technology. Some of the modern developments in this field are:
Numerical control (NC) and computer numerical control (CNC) machines and part programming: These machines use numerical data to control the motion and operation of metal cutting machine tools. Part programming is the process of creating and editing numerical data for NC or CNC machines. NC and CNC machines can perform complex and precise machining operations with high flexibility and automation.
Computer aided design (CAD) and computer aided manufacturing (CAM) systems: These systems use computer software to assist in the design and manufacturing of products. CAD systems can create and modify geometric models of products. CAM systems can generate and simulate machining programs for NC or CNC machines. CAD/CAM systems can improve the quality and efficiency of product development and manufacturing.
Non-conventional machining processes: These processes use other forms of energy to remove material from a workpiece without direct contact between the tool and the workpiece. Examples include laser machining, ultrasonic machining, electrochemical machining, etc. These processes can machine hard and brittle materials or complex shapes that are difficult or impossible to machine by conventional machining processes.
Smart machining systems and adaptive control: These systems use sensors, actuators, controllers and artificial intelligence to monitor and adjust the machining conditions in real time. They can improve the performance Conclusion

FAQs
What is the difference between orthogonal and oblique cutting?
Orthogonal cutting is a two-dimensional cutting process where the cutting edge is straight, parallel to the original plane surface on the workpiece and perpendicular to the direction of cutting. Oblique cutting is a three-dimensional cutting process where the cutting edge is inclined to the line normal to the cutting direction.
What are the advantages and disadvantages of continuous and discontinuous chips?
Continuous chips are chips that have a smooth and uniform shape and size. They are desirable for ease of chip disposal, steady cutting forces, good surface finish and low tool wear. However, they are undesirable in automated machinery because they can cause entanglement and damage to the machine or the operator. Discontinuous chips are chips that have an irregular shape and size. They are desirable for automated machinery because they can be easily removed by chip conveyors or vacuums. However, they are undesirable for fluctuating cutting forces, poor surface finish and high tool wear.
What are the main causes of tool wear and how to prevent it?
Tool wear is the gradual loss of material from the cutting tool due to various mechanisms such as abrasion, adhesion, diffusion, oxidation, etc. Tool wear can affect the quality and efficiency of metal cutting processes by reducing the tool life, the surface finish and the dimensional accuracy of the workpiece. Tool wear can be prevented or minimized by using appropriate tool materials, tool geometries, cutting conditions, cutting fluids, etc.
What are the benefits of using cutting fluids in metal cutting operations?
Cutting fluids are liquids or gases that are applied to the cutting zone to improve the metal cutting performance. Cutting fluids can provide various benefits such as reducing friction and wear, cooling and lubricating the tool and workpiece, removing chips and dust, preventing corrosion and oxidation, improving surface finish and dimensional accuracy, etc.
How to choose the best metal cutting machine tool for a specific application?
The choice of the best metal cutting machine tool for a specific application depends on various factors such as the type, shape, size and material of the workpiece, the required accuracy, quality and productivity of the machining operation, the available space, power and budget of the workshop, etc. Some general guidelines for choosing the best metal cutting machine tool are: use turning machines for cylindrical or conical surfaces, use milling machines for flat or curved surfaces, use drilling machines for holes, use grinding machines for smooth and accurate surfaces, use non-conventional machining processes for hard and brittle materials or complex shapes.
