Numerical control and robot systems surmount present-day industrial challenges

Introduction

Grigoriev S.N., Martinov G.M.  Tuning and diagnosis of metal-cutting machines using Web technologies

Improving manufacturing competitiveness requires shorter machine tool outages and timely preventive maintenance. Special stand-alone or NC-embedded toolkits for tuning machine tool drives and diagnosing inputs and outputs of relay ladder logic system respond to this challenge. Application of present-day Web technologies in control system software design enables remote tuning and diagnosis from machine tool vendor's fault-finding center. Geometric and logical control functions are the first ones to be diagnosed. An approach to building diagnosis tools based in virtual instruments integrated in a Web browser is offered.
