Planning feed speed in cold ring rolling
International Journal of Machine Tools and Manufacture, 2007Feed speed needs to be controlled during cold ring rolling but first it must be planned. However, up to now, it has been set mainly by trials and experience, as the existing method is inefficient. This paper aims to find a convenient method to plan feed speed.

The optimum log feed speed with bandsaw
European Journal of Wood and Wood Products, 2015A method is presented to determine the optimum log feed speed of a bandsaw based on its power consumption. Three timber species—oak, beech and pine—were sawn under real sawing conditions in a mill. The target of the experiment was to find the optimum log feed speed with the following characteristics: Minimum energy consumption per unit volume sawdust ...

THE SPEED FIELD FEEDING SYSTEM
1969Abstract : The SPEED Field Feeding System consists of a company-size kitchen and a brigade-size bakery. Both units are all-electric, mobile, and completely self-contained for one day's operation. A 60-kW gas-turbine generator set, similar to the type used on commercial aircraft as an auxiliary power source, is located in each unit, and is the sole ...

Feed, Speed, and Torque Controllers for Drilling
1993 American Control Conference, 1993The design and implementation of feed, speed, and torque controllers for drilling is discussed. Dynamic models of the feedrate drive and spindle motors were developed using experimental data and least squares estimation. These dynamic models were subsequently used to design closed loop feed and speed controllers, which allow for independent control of ...

Optimal Feed-Rate Scheduling for High-Speed Contouring
Journal of Manufacturing Science and Engineering, 2003The majority of efforts to improve the contouring performance of high-speed CNC systems has focused on advances in feedback control techniques at the single-axis servo level. Regardless of the dynamic characteristics of an individual system, performance will inevitably suffer when that system is called upon to execute a complex trajectory beyond the ...

Aerodynamic High Speed Feeding Systems: Flexible and Reliable
Manufacturing Engineering and Materials Handling Engineering, 2004Due to recent progress in automation technology, production systems can be realized which are able to assemble more than 600 parts per minute. The greatest problem at these high speeds is not machining itself, but the handling of the often disordered individual parts.

Integrated Design of High-speed Feed Drive Systems
Transactions of the Korean Society of Mechanical Engineers A, 2003High-speed feed drive systems have been widely used in the manufacturing and semiconductor industries. Specifications for high-speed systems require more advanced capabilities than conventional feed drive systems. It is necessary to devise special design concepts to achieve the level of performance for high-speed feed drive systems.

Optimum selection of machine tool speeds and feeds
International Journal of Machine Tool Design and Research, 1965Abstract The commonly used geometric progression of machine tool speeds and feeds is critically examined and found to provide uniform facility of tool life and surface finish control. A more important reason for adopting a geometric progression of speeds and feeds is that this leads to minimum manufacturing costs over the life of the machine if all ...
