Rockwell High Productivity and efficiency of the metal-working equipment, the quality and accuracy of machine parts is largely dependent on how the operating system associated with the cutting tool. In engineering for machining parts of machines use different types of instruments. The cutting tool attached to the workpiece the desired shape and size. Its efficiency and reliability have a significant impact on cost-effectiveness of engineering production. Operational characteristics of the cutting tools are highly dependent on the quality of the material from which these tools are made. Materials designed for cutting tools, a number of indicators should significantly exceed the materials used in engineering for manufacturing various components. Below are some basic requirements, applicable to the tool materials. 1. Tool material should have high hardness in delivery condition or attainable as a result of heat treatment - at least 62 65 hrc Rockwell (C Scale). 2. When cutting metals can be significant amount of heat, and the cutting part of the tool is heated. The temperature of the working surfaces and cutting edges of the instrument depends on the conditions under which being processed, and can reach several hundred degrees. It is necessary that at significant temperatures cutting tool surface hardness does not significantly decreased. Therefore, the tool material must have high heat resistance, ie ability to maintain high hardness at elevated temperatures and the original hardness after cooling. 3. Along with the heat-resistant tool material should...

Software AG '16 software QA day' in Nuremberg shows possibilities and current state of the technology model based testing (MBT) software QS day 16\"in Nuremberg model based testing (MBT) Nurnberg/Stuttgart shows possibilities and current state of the technology, October 06, 2008 - by the 5th November 07, 2008 the topic model based testing (MBT) revolves around in Nuremberg. Leading companies of the QS - like eXept Software AG - give a comprehensive overview on the current situation around the topic of MBT. Companies are nowadays more than ever facing the task to develop more complex products in shorter time intervals with consistently high quality the interest of the industry on the topic of MBT is therefore very large. A significant increase in the quality of test on the one hand, as well as time and resource savings in creation and maintenance of test on the other hand it is expected from this technology. In particular in the area of quality assurance it's therefore reinforced, a consistent and efficient test development and automation to make sure. The technology offers the best conditions to achieve this goal, the model-based test development, a practical application in the field of MBT. The test procedures are modeled thereby no longer programmed. These modeled test sequences can then execute directly as a model and evaluate. By the understandable through the model representation, even people with little programming knowledge can participate in test creation...
