When it comes to manufacturing various parts for different equipment—from flat washers for plumbing to aviation engine parts—several approaches exist. CNC (Computer Numerical Control) milling is a digital manufacturing technology. It uses special software to guide the equipment to produce highly precise components.
The majority of work for CNC parts manufacturing is done by programming completed separately from the machine, which is operated through automation. Manual milling, on the other hand, involves the work of a skilled operator.
While it may seem that CNC milling is an obvious choice for spare part manufacturing in the 21st century, many companies still use manual milling. What are their reasons for maintaining this older approach? Let’s review the benefits of each method.
