5. INTRODUABSTRACT  S ince the Industrial Revolution in the late 18th and early 19th centuries, the manufacturing process has undergone many dramatic changes. Revolution  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.machine tools manufacturing  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. computer-aided design computer-aided engineering

9. 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.

10. 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.

11. 2.5D Milling  CAM soft wares provide both interactive and automated 2.5D milling operations on CAD models.  Full tool path control and algorithms ensure that the user can manufacture the way he needs to.  Operations can be easily re-ordered, rotated, mirrored, etc..  Automatic feature-recognition and machining module automates the manufacturing of parts with multiple drills and complex holes.

12. 3D Milling:  CAM soft wares are providing 3D milling operations which can be used for both surface and solid models.  We can create machining strategies for roughing and finishing multi-surface models using several techniques.  We can specify boundaries to limit the cutting region, perform area machining of solid bodies or their cross sections, apply special algorithms for edge/flange finishing, and calculate tool path for helical circle milling.  Pencil cutting allows to machine sharp or filleted details even if they have not been filleted. CAM is very flexible to our machining operations working on both smooth mathematically correct geometry and triangulated models.  Mostly milling machining progresses through four stages, each of which is implemented by a variety of basic and sophisticated strategies, depending on the material and the software available.

13. 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.

14. Wire EDM  CAM software provides a EDM mechanism to machine any contoured mold, die, core, cavity, shape or profile.  CAM software supports 2D, 2.5D, 4D cutting of any complexity with circular interpolation of curves including two- contour machining.  The same features can be applied for water jet, laser or plasma cutting.

15. Turning:  CAM software automates our traditional turning "from roughing and grooving to threading and finishing" for faster, more accurate results, or to maximize our multi-axis machine tool investment.  CAM Software support for facing, boring, drilling, threading and cut off turning.  CAM supports several industry standard canned cycles tuned for various machining centers.

24. Automation and Use of Robotics  Through the use of CAM, a factory can become highly automated, using systems such as real-time control and robotics.  These processes are carried out by various robotic tools, such as lathes, milling machines and welding machines. welding  Each of the many manufacturing processes in a CAM system is controlled by computers, so a high degree of precision and consistency can be achieved that is not possible with machinery that must be controlled by people. Resource Management  Some CAM systems provide additional automation by also keeping track of materials used and automating the ordering process from suppliers or the delivery process from the manufacturer's inventory. suppliers inventory  This helps ensure that enough materials are always available to keep the manufacturing process on schedule.

25. People Still Needed  Although this might be true to some degree, the robotic machines that are commonly used in factories still require human workers.  Many workers have feared that the increased use of robotic tools would eliminate jobs in the manufacturing industry. manufacturing industry  The nature of those workers' jobs often change, however. Repetitive tasks are delegated to machines, and human workers' job descriptions move more toward things such as set- up, quality control, creating the initial designs and machine maintenance. quality control

26. 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.  A CAM system usually seeks to control the production process through varying degrees of automation.  CAM systems also can automate the process for requesting tool maintenance, repair or replacement.
