Abstract
Micro-machining technologies have been the subject of many studies and developments over recent decades due to their importance in the production of micro-moulds, micro-valves, medical components, micro-electrical-mechanical-systems, sub-miniature actuators, motors and micro-products generally. This chapter defines some key terms (in the context of micro-machining) and then outlines material considerations, challenges in obtaining the desired surface finish, simulation techniques, process and machine aspects of micro-machining, and it finally provides examples of micro-manufacturing sectors and applications.
Contributions from: David Shipley, Mark Strickland and Matthew Hutchinson.

Notes
- 1.
The cutting coefficient (also known as the specific cutting force) is the force, in the cutting direction, required to make a cut with a cross sectional area of 1 mm2 and a chip thickness of 1 mm, for a specific cutter and material combination.
- 2.
A non-linear spring element is a special structural element that only has a specified spring stiffness, and can be placed between two nodes or between one node and the “ground” to exert a force on the node(s) based on the relative displacement.
- 3.
The atomic-scale finite element method [14] is not a multi-scale method.
- 4.
A trochoid (derived from the Greek word for wheel, “trochos”) is the curve described by a fixed point on a circle as it rolls along a straight line.
- 5.
In machining terms, meso-scale generally refers to the scale spanning micro and macro-machining.
