Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) – Encyclopedia – Business Terms

Computer-aided design (CAD) involves creating computer models defined by geometrical parameters. These models typically appear on a computer monitor as a three-dimensional representation of a part or a system of parts, which can be readily altered by changing relevant parameters. CAD systems enable designers to view objects under a wide variety of representations and to test these objects by simulating real-world conditions.

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. These systems differ from older forms of numerical control (NC) in that geometrical data are encoded mechanically. Since both CAD and CAM use computer-based methods for encoding geometrical data, it is possible for the processes of design and manufacture to be highly integrated. Computer-aided design and manufacturing systems are commonly referred to as CAD/CAM.

The vision of Computer-Aided Programming is to
use the power of automatic reasoning to simplify the task of programming.
Here, rather than manually reasoning
about programs, the programmer uses a program verifier to automatically find proofs
program correctness or incorrectness. Rather than directly coding up executable programs, the
programmer writes a specification of the structure and function of a program, letting
an algorithm for program synthesis generate correct low-level code.

All this may sound too good to be true, as
verification and synthesis are easily seen to be as hard as the Halting

for Turing machines.
However, over the last few decades, our field has developed many
algorithms and
tools that either solve these problems approximately,
or alternatively, solve them exactly for important classes of programs. Some of
these tools are now routinely used by program designers.
