In this paper, we investigate the servo parameters and axis dynamics influences on the contouring accuracy for practical applications such as contouring control of manufacturing systems (robot, ...machine tool...). The analytical formulation of contouring error in the case of straight line, circle and corner crossing is derived using a simplified axis drive model including the main servo parameters and dominating mechanical mode. The effectiveness of the proposed formulation in estimating the evolution of the final contour error is demonstrated experimentally on a two-axis machine tool.PUBLICATION ABSTRACT

Fifty years ago this month, Gordon Moore forecast a bright future for electronics. His ideas were later distilled into a single organizing principle- Moore's Law-that has driven technology forward at ...a staggering clip.
One of the axiomatic, premises for marketing success is realizing and understanding customer needs and interests. In fact, a basic concept of marketing is that a firm solely exists to satisfy the ...needs and wants of the consumer. Therefore, a major challenge of marketing is to discover and understand a client's desires and interests in order to satisfy them. This becomes even more significant when dealing with Internet customers who have come to expect more personalization and customization from products and services than ever before. While a marketer can measure the amount of hits a Web site receives, and even from which computer the hits are coming, it is impossible to know who is actually moving the mouse. This creates a paradox for market researchers, since without accurate or sufficient consumer knowledge, opportunities or trends cannot be clearly identified, which in turn makes it difficult to satisfy the customer's needs. The result is a gap between what the market researcher believes the consumer wants, and what the consumer actually requires. Narrowing this gap for online consumers has been an ongoing endeavor that currently uses several methods to track a user during Web site visits. Cookies, login accounts, smart cards, credit cards, and digital certificates are collectively referred to as the "traditional method" for online marketing, but essentially are ineffective at associating Web site behavior to a particular consumer
