Summary
The term CAD means Computer-Aided Design and CAM refers to Computer-Aided Manufacturing (CAM). CAD software is used for drawing tools basically to explain the geometries which are used by the manufacturing portion, i.e. the CAM part of the program. It explains the path that helps directing the motion of a machine tool, to the machine in the exact shape drawn.

Download file to see previous pages It was in the 1950's that the Numerically-Controlled machines were based upon the technology of paper tapes which had proper spaced holes punched into the papers. it is similar to the paper roll which makes piano works having only an inch width which is used to feed the numbers into controller machines. These are wired to join the motors positioning work over the machine tools. These controllers are electro mechanical that allows easy incorporation of the digital technologies in their original form.
During the period of late 1960's these Numerically-Controlled machining centers were very easily available for the commercial incorporation of a variety of machining processes, and also enabling the automatic tool changing process.
So these tools were capable of performing any work on the many faces of any kind of work further enabling the movement of the work piece to the specified positions which were previously programmed. This programming was done making use of a variety of automatic tools. Thus making it possible to do the same piece of work over and over, automatically with perfection and very little human input. The NC was immediately automated giving a newer level of manufacturing. The incorporation of feedback loops was also done.
The development of APT was a breakthrough in the success of the NC technology which is a universal NC programming language. The Automatically Programmed Tools developed in1962, enables the programmers to develop the postprocessors, tailored to each type of NC tool. This helped in the output sharing between different units having different manufacturing capabilities.
CAD and CAM Together now:
CAD basically uses the software known as TTUA (http://en.wikipedia.org/wiki/CAD/CAM). It assists engineers, architects, designers in their activities. This geometrical tool in the Product Lifecycle Management (PLM) also involves a special hardware. These tools are used and incorporated in almost every sector like manufacturing, designing, planning etc using the tools CIM, CAPP, FMS, and JIT etc.
The development of Computer-aided design had its effect on the NC technology due to the differences in the formats of various files which were used initially by the drawing and manufacturing programs.
" in the CAD world, we take a pencil out of the hand of the operator and place it into the hand of the computer" (Jan Bone,1994). With the newer and variety of CAD applications like Solid Works and Auto Cad and CAM applications like Master Cam, both designing and manufacturing sectors now use these variety of CAD/CAM software. Most of the CAD/CAM software are used more by architects these days, along with product designing and manufacturing.
Future trends in CAD/CAM:
Though the current CAD/CAM applications are much user friendly and satisfactory, and people do not think there is nay need for advances in the same, but the coming decade will have many advances in techniques and implementation of CAD/CAM, for the creation and manipulation of the work piece geometry.
The standards for its applications will give more flexibility to its users in the interfaces, data transfer, computer designing and architecture etc. thus it can be said that these future developments will have a solid impact on both, the numerical control system and the manufacturing applications.
By anticipating the basic questions like what is the direction of NC and CAD/CAM What are the ...Download file to see next pagesRead More
