In this Fab Academy session, Tony Schmitz and Tom Bodett introduce the fundamentals of computer-controlled machining, exploring how CNC machines transform digital designs into large-scale physical objects.

From precision metal cutting to digital woodworking, students learn the mechanics, programming, and design strategies needed to fabricate complex parts safely and efficiently.

🛠 What You’ll Learn

⚙️ CNC Machine Fundamentals

How CNC machines work

DC motors, ball screws, and machine motion systems

Types of milling configurations

Tool geometries and end mill design

Up milling vs. down milling strategies

🧰 Cutting Tools & Machining Parameters

Understanding flutes and tool shapes

Speeds and feeds calculations

Managing vibration in machining setups

CAM programming and toolpath generation

Using G-code and M-code to control CNC machines

🪵 CNC Woodworking & Joinery

Tom Bodett demonstrates how CNC machines are used in digital woodworking, highlighting:

The importance of wood grain direction

Choosing the right cutting tools

Avoiding tear-out during milling

Joinery techniques like mortise and tenon and floating tenons

He also shares a real-world project producing museum display cases using CNC machining.

📐 Weekly Assignment

Students will:

🔹 Characterize CNC machine performance
🔹 Test machining parameters
🔹 Design a large-scale press-fit construction project
🔹 Create 3-axis CNC toolpaths for fabrication

Safety is also emphasized, including proper protective equipment and safe machine operation.

🚀 Computer-controlled machining allows makers to build furniture, structures, machines, and large-scale prototypes directly from digital designs.
