Now we have to investigate the relating methods and topics that possibly help us find a solution.
The goal is to find the most efficient way to bring low volume, accurate, fast turn around manufacturing in house.
4 axis CNC Milling/Routing:
CNC stands for Computer numerical control.
Numerical control is the automated control of machining tools and 3D printers by means of a computer. An NC machine alters a blank piece of material (plastic or thermoformed plastic ) to meet precise specifications by following programmed instructions and without a manual operator.
Computer Numerical Control is different from typical PCs in the type of software used to control the machine, which is specially customized and programmed with G-Code — a specific CNC machine language that allows precise control of features like speed, location, coordination and feed rate.
A 4-axis CNC machine operates on the X,Y and Z axes like a 3-axis machine, but it also includes rotation around the X-axis, which is called the A-axis. This is the 4th axis that's added to our machining process. In most cases, the workpiece will be rotated to allow for cutting to occur around the B-axis.
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. It could be done varying direction on one or several axes, in our case it would be 4 axes.

The design process follows the same basic production stages which all CNC machining processes do, including:
1.Designing a CAD model
2.Converting the CAD model into a CNC program
3.Setting up the CNC milling machine
4.Executing the milling operation
Speed, production rate, and accuracy are some of the main advantages of CNC machining over conventional machining.
CNC router is designed to process softer materials can fall under a wide range – wood, plastic and even softer metal like aluminium, whereas CNC milling, is more capable of dealing with almost any type of material with higher density.
When cutting softer materials in larger sheets, CNC routers are not normally as precise as milling machines. Milling machines can cut as close as 1,000th of an inch when cutting metal. On the other hand.CNC routers cut at a higher speed than milling machines.
additionally, CNC routers can operate on a horizontal or vertical configuration. CNC routers usually have shallow clearance because they are designed to cut flatter materials.
CAD(computer-aided design) needs to be converted.CAM software makes the CAD drawing/design into a code called g-code. This code the CNC machine can understand. In short, CNC technology is not very complicated. It is a tool controlled by a computer. It only becomes more sophisticated when considering how the computer controls the tool.
Computer Aided Manufacturing (CAM) is the use of software and computer-controlled machinery to automate a manufacturing process.
Three components are needed for a CAM system to function:
Injection Moulding can be one of the solutions.
Plastic injection moulding is the process of melting plastic pellets (thermosetting/ thermoplastic polymers) that once malleable enough, are injected at pressure into a mould cavity, which fills and solidifies to produce the final product.
it is a fast process and is used to produce large numbers of identical items from high precision engineering components to disposable consumer goods.

- Software that tells a machine how to make a product by generating toolpaths.
- Machinery that can turn raw material into a finished product.
- Post Processing that converts toolpaths into a language machines can understand(G-code).
