Some important parameters of the machine tool layout have to be selected in the early stages of design when a shortage of information makes application of the finite element method impractical. As a computeraided tool in these stages, the formshaping function (FSF)based approach can be used.

plications. It enables machine vision to be used for a variety of functions, including: identification of shapes, measurement of distances and ranges, gaging of sizes and dimensions, determining orientation of parts, quantifying motion, and detecting surface shading. Several examples of machine vision applications are shown in Fig. 3.
PHASES OF A MINING PROJECT There are different phases of a mining project, beginning with mineral ore exploration and ending with the postclosure period. What follows are the typical phases of a proposed mining project. Each phase of mining is associated with different sets of environmental impacts. Exploration

Grinding flat or plane surfaces is known as surfaces grinding. Two general types of machines have been developed for this purpose; those of the planer type with a reciprocating table and those having a rotating worktable. Each machine has the possible variation of a horizontal or vertical positioned grinding wheel spindle. The
