What are the differences between CNC Turning and Milling?

CNC turning is a manufacturing process that relies on a computer program to remove portions of material from a workpiece and create desired parts. The process starts with you making a 3D CAD model of your desired part before converting it into G-code (computer program) using computer-aided manufacturing (CAM) software. The G-code then automates the operation of the cutting tool and workpiece to create your desired shape.

CNC milling is a form of manufacturing that involves removing material from a workpiece to create a finished shape. The CNC milling process starts with you making a 3D CAD model of your desired part geometry before converting it to a computer program (G-code) using CAM software. This computer program then automates the operation of the cutting tool to create your desired parts.

Q: How do you design CNC machining parts?
A: Designing CNC machining parts involves several key steps to ensure accuracy, manufacturability, and functionality. A basic guidance includes defining requirements, selecting CAD software, choosing material, designing for manufacturability (DFM), tolerances and fits, toolpath generation, simulation and verification, prototyping and testing, documentation, and iteration and improvement.

Q: How to make a CNC machine from a printer part?
A: The process includes assessing the 3D Printer, researching and planning, selecting a CNC conversion kit or components, modifying the frame and structure, replacing or modifying the extruder, upgrading electronics and firmware, installing CNC software, calibration, testing, safety considerations, experiment, and iteration.
