CNC milling is the most popular CNC machine architecture. In fact, the term CNC milling is often synonymous with CNC machining. CNC milling machines use rotational cutting tools to remove material from a part mounted on the machine bed. Most CNC milling systems have 3 linear degrees of freedom: the X, Y and Z axes.

Assume you have an assembly line with 10 machines. Each machine can function at a 90% uptime rate. Each machine may fail at random times, or mutually exclusive from one another. The resulting reliability of the line with 10 machines at 0.9 (90%) reliability each is 35%. This means that some portion of the assembly line could be down 65% of the ...

The end relief (clearance) angle is the angle ground below the nose of the toolbit, which permits the cutting tool to be fed into the work. It is generally 10° to 15° for general-purpose tools (Figs. 29-4 and 29-5). This angle must be measured when the toolbit is held in the toolholder. The end relief angle varies with the hardness and type ...

Researchers recently used AI to measure the quality performance of a CNC milling machine. Their approach used machine learning to detect acoustic signals and match those indicators with excellent or poor-quality performance. The algorithms could suggest when to replace a part, as well as evaluate the amount of wear on a machine.
