Chapter 7 The Spatial Structure of Urban Areas

7 The Spatial Structure of Urban Areas 71 INTRODUCTION In this chapter we are concerned more specifically with spatial relations within the individual urban or metropolitan area 1 Such an area includes a principal city with an intensively developed core or downtown area the central business district or CBD and a surrounding fringe of suburbs and satellites linked to the principal city

Milling is the most common form of machining a material removal process which can create a variety of features on a part by cutting away the unwanted material The milling process requires a milling machine workpiece fixture and cutter The workpiece is a piece of preshaped material that is secured to the fixture which itself is attached

The use of conventional manufacturing methods is mainly limited by the size of the production run and the geometrical complexity of the component and as a result we are occasionally forced to use processes and tools that increase the final cost of the element being produced Additive manufacturing techniques provide major competitive advantages due to the fact that they adapt to the
