CNC Machining Basics: Processes, Setup & Surface Quality https://rcjmzg.com/blog/machining-basics/ Thu, 03 Sep 2026 04:19:10 +0000 en-US hourly 1 https://wordpress.org/?v=7.1.3 https://rcjmzg.com/wp-content/uploads/2025/12/favicon-150x150.png CNC Machining Basics: Processes, Setup & Surface Quality https://rcjmzg.com/blog/machining-basics/ 32 32 CNC Machining Guide for Engineers: Processes, Materials, Tolerances and Cost https://rcjmzg.com/cnc-machining-guide-for-engineers-processes-materials-tolerances-cost/ Wed, 12 Aug 2026 03:56:02 +0000 https://rcjmzg.com/cnc-machining-guide-for-engineers-processes-materials-tolerances-cost/ CNC machining spans milling, turning, and 5-axis work, but the real engineering decisions happen in material selection, tolerance specification, and how those choices ripple into cost. This guide breaks down the process trade-offs engineers actually need to weigh before releasing a drawing.

Here's how to tell which process actually belongs on your drawing before you send it out for quotes.

Here's what actually causes the distortion, and the fixturing fixes that stop it before it starts.
