CNC Machining vs Manual Machining - Part 2

January 6, 2021 3:39 pm

 

Is CNC machining always more efficient than manual machining? We machined the same part using CNC and manual machines to find out.

There is no doubt that CNC machining has great advantages over manual machining. To name a couple, CNC machining minimizes the amount of interaction between the operator and the machine tool, and significantly reduces the active machining time. But is this always the more efficient or fastest way to get a part done? And can a part made with a CNC machine be done using manual equipment?

Derrick Hogan, CNC technology instructor at North Georgia Technical College, helped us answer these questions. In these two videos, he showed us how to machine the same part using CNC machines and manual machines and helped us find out which process is faster.

This video (part 2) shows how the part is finished on the manual mill. Check out the first part of the video to see how the CNC machined part was programmed cut and how the manual part was initially cut using a manual lathe.
