Abstract:
Precision machinery has come a long way over the years. Factories that once relied on manpower now use machines, and this development has brought with it innumerable benefits including improvements to accuracy, repeatability, productivity and efficiency. Naturally, though, machines are imperfect in that precision of a batch of machines vary slightly. On top of that, machines experience wear and tear or even break-downs. These unpredictable events can be costly to manufacturers. This is why research to better understand factors that affect a machine's precision is important. This knowledge can

Magnetic suspension technology is used in CNC machine tool. The guide which uses the electromagnetic force is suspended in the air without mechanical touch. There is no mechanical contact with the supporting components. It can eliminate friction and wear. Magnetic suspension structure guide can achieve fast and precise position, and increase the productivity of the equipment substantially. Magnetic suspension structure guide has a lot of significant advantages. The magnetic suspension rail can ensure the high positioning accuracy of machine tools platform from the structure, and reduce the ine

Abstract. The prediction of agricultural machinery’s fatigue life is of increasing importance for machine developers who must produce durable and reliable machines for a globalized market with different local operating conditions. Mathematical tools that can model and simulate the variable loading of agricultural machines are necessary for fatigue life prediction. Modeling should be based on measured loads from real-world operations. In this article, the loads of a four-rotor rake were recorded during grass swathing. Markov chains were used to model the transitions between the machine’s operat

The globalization of the economy and the competition between emerging countries has compelled machinery manufacturers in developed countries to have new production methods in an environment of "consensual" standardization and extensive regulation. However, very little research has focused on the use of these standards and regulations. This empirical exploratory study aims to develop a profile of the adoption and use of normative and regulatory documents by Québec machinery manufacturers.

Rotating unbalance is a costly source of harmful vibration affecting a wide variety of applications such as high-speed machine tools and turbomachinery. Active balancing technology allows adjustment of a machine’s balance state while conditions change as the machine continues to operate. An adaptive control law for single-plane active balancing is presented here for control of steady-state rotation-synchronous vibration. The adaptive control method, based on the well known “influence coefficient” approach, requires no a priori modeling or estimation of plant dynamics. A control “gain” paramete

Abstract. Most modern off-road machinery use embedded electronic controllers connected to a controller area network (CAN) to broadcast machine information for on-board processes and diagnostics. Commercially available tools can record CAN data for a variety of research and commercial uses. For agricultural tractors, there is an opportunity to create advanced test procedures that are more representative of field operations and that could supplement existing machine performance tests, such as the OECD Code 2 Standard Code for the Official Testing of Agricultural and Forestry Tractor Performance.

In machining process, tool wear is an inevitable consequence which progresses rapidly leading to a catastrophic failure of the system and accidents. Moreover, machinery failure has become more costly and has undesirable consequences on the availability and the productivity. Consequently, developing a robust approach for monitoring tool wear condition is needed to get accurate product dimensions with high quality surface and reduced stopping time of machines.
