ABSTRACT
Since the Industrial Revolution in the late 18th and early 19th centuries, the manufacturing process has undergone many dramatic changes.
One of the most dramatic was the introduction of computer aided manufacturing (CAM), a system of using computer technology to assist in the manufacturing process.
This technology began to be developed in the 1950s, and by the 1970s, it was being used by some large manufacturers by the early 21st century, computer aided manufacturing had become an integral part of the manufacturing process in many industries (CAM) is the use of computer software to control machine tools and related machinery in the manufacturing of work pieces.
Its primary purpose is to create a faster production process and components and tooling with more precise dimensions and material consistency, which in some cases, uses only the required amount of raw material (thus minimizing waste), while simultaneously reducing energy consumption.
CAM is a subsequent computer-aided process after computer-aided design (CAD) and sometimes computer-aided engineering (CAE), as the model generated in CAD and verified in CAE can be input into CAM software, which then controls the machine tool.
CAM Definition
Computer aided Manufacturing(CAM) is assistance of computer in manufacturing planning and processes like planning different operations to be done on product, sequencing all the operations and finally control the machine parameters like Feed, Speed, Depth of cut etc.
CAM uses CAD data to control automated machinery.
CAM systems are associated with computer numerical control (CNC) or direct numerical control (DNC) systems. These systems differ from older forms of numerical control (NC) in that geometrical data is encoded mechanically.
3-DPrinting
A subset of SLA, 3D printing depends on layering and connecting different cross-sections in order to offer a speedy and affordable alternative to more expensive types of model fabrication.
This method is ideal for early stages of product design, when visualization is key and structural integrity is less important, because the resulting components tend to be weaker than other fabrication methods’ results.
5-Axis Milling:
Simultaneous 5-axis machining is becoming more and more popular due to the need for reduced machining times, better surface finish and improved life span of tools.
CAM software utilizes all the advantages of Simultaneous 5-Axis machining and together with collision control and machine simulation, provides a solid base for 5-axis solution.
CAM software provides intelligent and powerful 5-axis machining strategies, including swarfing and trimming, for machining of complex geometry parts including mold cores and cavities, aerospace parts, cutting tools, cylinder heads, turbine blades and impellers.
CAM software provides a realistic simulation of the complete machine tool, enabling collision checking between the tool and the machine components.
Benefits of CAM:
Improve productivity.
Time reduction
Improve accuracy of product.
Reduce training time for routine drafting tasks and NC part programming.
Reduce engineering personal requirements.
Fewer errors in NC part programming.
Provide the potential of using more existing parts and tooling.
Helps ensure design is appropriate to existing manufacturing techniques.
Saves material and machining time by optimizing algorithm.
Provides operational results on the status of work in progress.
Makes the management of design personnel on project more effective.
Better communication interfaces and greater understanding among engineers, designers, drafters, management and different project groups.
CONCLUSION
Computer-aided manufacturing (CAM) uses geometrical design data to control automated machinery.
CAM systems are associated with computer numerical control (CNC) or direct numerical control (DNC) systems.
When and where the CAM was used at advance technologies such as robotics, industries.
