Modern manufacturing relies on three basic services: high-quality machined parts, comprehensive machining services, and rapid CNC machining prototyping capabilities.

Metal components are unique across industries. Engineers and designers must understand the part's material, production process, and application in order to select the appropriate manufacturing method.

The manufacturing processes for metal parts vary. Each method offers unique advantages, suitable materials, and trade-offs. A deeper understanding of the characteristics of different production methods will help optimize this decision-making process.

This is an overview of 8 different manufacturing processes you can utilize to create custom metal parts. These are:

1. CNC milling and CNC turning
2. Extrusion
3. Metal casting
4. Die casting
5. Metal injection molding
6. Forging
7. Sheet metal and stamping
8. Metal 3D printing

CNC Milling and Turning

CNC machining technologies primarily include two types: CNC milling and CNC turning. A CNC milling machine is an automated cutting machine that uses a rotating spindle head to remove excess material. The material is then machined into the desired shape by rotating a fixed tool. This technology is suitable for a wide range of materials, including plastics, aluminum, stainless steel, and titanium.

CNC machining and turning work as follows:

CNC Turning
CNC turning relies on CNC lathes or multi-axis CNC turning centers. Manufacturers use CNC lathes to machine cylindrical and concentric features on parts. Live-die lathes combine end mills and drills, enabling the machining of off-axis features without changing equipment.

Swiss Machines
These specialized CNC lathes, often called Swiss machines, are designed to quickly produce small parts with complex features by integrating multiple tools and spindles within the machine.

A typical lathe removes features by rotating the workpiece on a central axis and using rigid cutting tools. Lathes can also perform other functions, including making internal and external threads, creating flange features, machining O-ring grooves, and knurling textures.

CNC lathes and CNC milling machines have different axis configurations. CNC lathes are typically single-axis, three-axis, or four-axis machines. Three-axis CNC machining processes material in the X, Y, and Z axes, while simultaneously removing excess shavings in all three directions. Four-axis machines include lathes and tilting mills capable of machining concentric features. Lathes are well-suited for producing round parts, but machining irregular shapes and sharp edges is more complex; milling machines are relatively superior at handling these complex shapes.

Modern CNC technology supports up to five-axis machining. These tools add tilt and rotation capabilities to the traditional X, Y, and Z axes, enabling more precise cutting of complex parts. Five-axis machining not only improves accuracy but also increases efficiency, as it allows more part features to be machined in a single operation. Milling machines typically come in a variety of configurations, including three, four, and five axes, to suit varying machining needs and complexity.

CNC stands for Computer Numerical Control. Operators control CNC milling and lathes using G-code, a programming language that provides instructions for machine movement. Modern programming instructions are typically generated using computer-aided manufacturing (CAM) software. G-code dictates where the machine's tool head should move, while also controlling its speed and feed rate, including rotational speed, depth of cut, and workpiece movement. The complexity of the G-code depends on the number of axes on the machine and the tool set used.
