Introduction
Computer-aided manufacturing (CAM) is a process that utilizes computer technology to assist in the manufacturing process. It involves the use of computers to generate and analyze data from computer-aided design (CAD) and computer-aided engineering (CAE) systems. It is used to improve the accuracy and efficiency of the manufacturing process.
History
CAM was first used in the late 1950s, when computers began to enter the workplace. Programmable logic controllers (PLCs) were introduced in the early 1960s as a way to control automated machinery. The first CAM system was implemented in the early 1970s, and since then, CAM systems have become increasingly sophisticated.
Types of CAM Systems
There are several types of CAM systems that are used in various manufacturing processes. The most common types are:
1. Numerical Control (NC): NC systems use numerical data to control automated machine tools. The data can be input into the system manually or from a CAD or CAE system.
2. Direct Numerical Control (DNC): DNC systems are similar to NC systems, except that the data is transmitted directly from one computer to another. This eliminates the need for manual input.
3. Computer Aided Process Planning (CAPP): CAPP systems use a combination of CAD/CAE data to generate process plans that provide instructions to a manufacturing system.
Benefits of Using CAM Systems
CAM systems have a variety of benefits that make them desirable in many manufacturing environments. Some of the most common include:
1. Increase Efficiency: CAM systems can improve the accuracy and speed of the manufacturing processes that are involved, resulting in more efficient production times.
2. Cost Savings: By reducing the amount of manual labor that is needed, CAM systems can reduce costs for the manufacturer.
3. Quality Control: By using data from CAD/CAE systems, CAM systems can be used to ensure that the manufactured product is of high quality.
Conclusion
Computer-aided manufacturing is a process that uses computer-generated information to assist in the manufacturing process. It is used to improve accuracy and efficiency, resulting in cost savings for the manufacturer. There are several types of CAM systems, each of which has its own advantages and disadvantages. However, the overall benefits of using CAM systems, such as improved efficiency, quality control and cost savings, make them an attractive option for many manufacturers.
