In conventional milling, special cutters are used to shape and rotate against the direction of the feed. The conventional method is the more traditional approach to machining, primarily because “backlash” is eliminated. Conventional milling can also be performed by varying the direction of the cutters on one of several axes, adjusting cutter head speed, and by changing cutting depth.
ADVANTAGES OF CONVENTIONAL MILLING
- Considered the preferred method for less complicated applications.
- Sometimes preferable when cutting ¾ to 1 times the cutting diameter.
ORIGINS AND DEVELOPMENT
The first true milling machine can be directly attributed to Eli Whitney, the inventor of the cotton gin. In the late 18th century, Whitney was hired by the American government to create large quantities of firearms and he needed a machine capable of reproducing many identical and interchangeable machined parts.
While still used at Cadorath for specific applications, conventional milling is slowly being replaced by highly accurate and less time-consuming methods, such as CNC milling.
