Part programs can be prepared in less time, easing the burden on overworked programming departments and eliminating a major bottleneck in work flow. With computerized feature recognition, programmers can be more productive, relieving pressure on shops that can't find enough qualified programmers. Automating or streamlining this process is a big help to the programmer. Feature recognition means identifying the design geometry that represents holes, slots, pockets, bosses, fillets, chamfers and other design elements that can be machined. Feature recognition technology is an emerging tool for this purpose.
In the world of CNC machining, this essential job of interpreting design data usually falls to the CNC programmer.ģ Today, many developers are working on ways to automate these interpretive steps. Part features as represented in design geometry must be identified correctly and linked with the appropriate machining strategy because nobody wants to end up making white elephants on the shop floor. In manufacturing, of course, there is no room for anything but being entirely right about how to machine a workpiece in order to fulfill the designer's intent. Each of the blind men is partly right and each is partly wrong, the poem concludes. Another proclaims that the elephant's floppy ear is very like a fan, and so on. The one who catches the trunk says that an elephant must be very like a snake. The one who grasps the tail insists that an elephant must be very like a rope. The one who feels the tusk declares that an elephant must beĢ very like a spear. Each one touches a different part of the animal's body. A famous poem based on a fable from India describes six blind men who encounter an elephant for the first time.
