# Machining Processes
## Advantages of Machining Processes
- High precision of geometrical dimensions, tolerances, and surface finishes
- Is able to make one off prototypes in production grade material
- Creates high volume production tooling
- Increasing hard/brittle/fragile/tough materials can only be machines
- Some designs are so complex that machining is the only realistic process to make them with
## Disadvantages of Machining Processes
- Material is wasted (as it is a subtractive process)
- Complex parts require expensive machines to make and making them can take a long time
- Parts need to be set up using fixtures. These fixtures get increasingly complex with the part.
- Faster production rates and harder materials wear down the tools.

[^d_deflocculant]: a substance which, when added to scattered particles in suspension, causes a reduction in apparent viscosity. Deflocculants are substances which prevent flocculation by increasing zeta potential and therefore the repulsive forces between particles.
