<h4>Numerical Control</h4>


<p>Numerical control (NC) is a method of controlling the motions and actions of machines or devices using numerical data or instructions. NC can be used to automate various manufacturing processes or operations that require high precision, accuracy, and repeatability. NC can also improve the productivity, efficiency, and flexibility of manufacturing systems.</p>


<p>NC systems consist of three main components: an NC machine or device that performs the physical work on a workpiece or material an NC controller unit that interprets and executes the NC program or instructions and an NC feedback system that monitors and regulates the NC machine or device. There are different types of NC systems based on the level of control and complexity of the NC program or instructions. Some of these types are: - Point-to-point (PTP) system: It is a type of NC system that controls only the position of the machine or device in discrete points. It does not control the speed or path of the machine or device between the points. PTP systems are used for applications such as drilling, punching, tapping, etc. - Straight-cut system: It is a type of NC system that controls both the position and speed of the machine or device along straight lines. It does not control the path of the machine or device along curves or contours. Straight-cut systems are used for applications such as milling, turning, boring, etc. - Contouring system: It is a type of NC system that controls both the position and speed of the machine or device along any desired path, including curves and contours. It is the most advanced and versatile type of NC system. Contouring systems are used for applications such as machining complex shapes, cutting profiles, engraving, etc. <h5>Computer Control of Manufacturing Systems</h5>


<p>Computer control of manufacturing systems is the use of computers to monitor and regulate various aspects of manufacturing processes and operations. Computer control can improve the quality, efficiency, flexibility, and integration of manufacturing systems. Computer control can also enable the implementation of advanced manufacturing concepts such as computer-integrated manufacturing (CIM) and flexible manufacturing systems (FMS).</p>


<p>CIM is a concept that involves the integration of all the functions and activities involved in manufacturing using computer technology. CIM aims to create a seamless flow of information and control among different stages and departments of manufacturing, such as design, planning, scheduling, production, quality control, inventory management, distribution, etc. CIM can also integrate manufacturing with other functions such as engineering, marketing, finance, etc.</p>


<p>FMS is a concept that involves the use of computer-controlled machines or devices that can perform various tasks on different workpieces or materials with minimal human intervention. FMS aims to create a flexible and adaptable manufacturing system that can respond quickly and efficiently to changing customer demands or market conditions. FMS can also reduce setup time, waste, and cost by using modular, reconfigurable, and interchangeable machines or devices.</p>
