What is CNC Milling?
Milling machines use cutting tools to shape workpieces through subtractive means: whittling away metal, plastic, or other materials. The history of milling is rich and full of famous figures and places.
Early forms of subtractive machine tools, like lathes, were possibly used by the ancient Egyptians more than 3,000 years ago. Various milling-type machines appeared in the 1700s, and in 1774 the British inventor and industrialist John “Iron Mad” Wilkinson developed one such device to bore iron cylinders for cannons and James Watts’ steam engines.
From Punch Cards to Artificial Intelligence
As the century wore on, numerical control was developed, using punch cards to automate machine processes. Then in the mid-20th-century, the birth of CNC occurred (we can link to the previous “What is CNC Machining?” blog here) and has since led to computer-controlled precision with endless potential. Thanks to this intelligent automation, milling has become so accessible, effective, and safe that even hobbyists can easily obtain some version of this world-building technology.
In industry, milling exponentially simplifies all fabrication. Through computer guidance, complex shapes are not only possible but infinitely reproducible. And at unprecedented production rates, because in this era of automated machining, precision is no longer sacrificed for speed or volume.
CNC Mills Come In Various Forms
The mills of old were lucky to feature a couple of axes, but the intelligent mechanical beasts of today utilize 5 axes. With varying degrees of mobility, the most geometrically convoluted cuts are simpler than ever. There are virtually no limitations—as we like to say, “if you design it, we can mill it.”
And with ultra-fine tolerances of +/- 0.002 inches, we can reliably produce super-delicate components for various industries. And when human lives are in the balance, as in the medical and aero sectors, perfection is the only option.
Computer Control Opens a World of Manufacturing Possibilities
The computerized behind-the-scenes processes do more than guarantee an accurate cut, though they do that exceedingly well. Computer-aided design (CAD) and diverse analytical tools help devise more efficient forms for machined components. As well as more efficient means for production, making optimal use of material while reducing waste, labor, and prices.
Virtual advances also allow pre-cut simulations. This ability shows us what the finalized piece will look like and provides a chance to make any alterations. The yet-to-be-manufactured items can also be tested through computerized means to check their structural integrity and efficacy. Afterward, any desired improvements can then be made with unfailing precision.
