Direct influences applied to the mill drive system For the QdX4TM Mill Drive system, exhaustive research was conducted to identify all the parameters influencing the entire kinematic chain. These were evaluated for both the drive and the mill itself throughout the life of the system, so that no single parameter would be ignored.

Multi-stand rolling mill with a device for protection against overloads due to irregularities in the feed of the rolled product, comprising a kinematic chain for transmitting motion to the stands from at least one drive means, with an individual drive shaft for each stand and a coupling between each of the drive shafts and the respective rolling stand.
A mini hot strip mill comprises three close coupled mill stands including a first and second four high finishing mill and a two high roughing mill positioned therebetween. A first coiler furnace is positioned upstream and a second coiler furnace is positioned downstream of the mill. The mills may each be retained in their own mill housings or the finishing mills may be in separate housings and ...
Kinematic synthesis, on the other hand, is the process of designing a mechanism to accomplish a desired task. Here, both choosing the types as well as the dimensions of the new mechanism can be part of kinematic synthesis.

With manufacturing industry tending to high-mix low-volume production, the turn-mill machining technology has recently received much attention. This research proposes the programming method using process planning and kinematic based on the existing problems during the course of the programming for the mill-turn machine. Firstly, through computing the volume of removal shape on the cylindrical ...
In mechanical engineering, a kinematic chain is an assembly of rigid bodies connected by joints to provide constrained (or desired) motion that is the mathematical model for a mechanical system. As in the familiar use of the word chain, the rigid bodies, or links, are constrained by their connections to other links.An example is the simple open chain formed by links connected in series, like ...
The 508MT2 is a multi-process machining center dedicated to machining complex parts from bar stock or in one-piece mode. It is equipped with a swiveling powered spindle fitted on a B-axis and a high-precision A-axis spindle/divider enabling turning operations up to 6,000 rpm.

Kinematics is the study of the motion of bodies (objects) and systems (groups of objects), while ignoring the forces that cause the motion. The movement of a crane and the oscillations of a piston in an engine are both simple kinematic systems. The crane is a type of open kinematic chain, while the piston is part of a closed four-bar linkage.
The rotary axes are here in the beginning of the kinematic chain, resulting in a much larger machine tool workspace then for model I. Also there is much less interference of the machine tool workspace with the slides. The other 18 possible kinematic chain selections will give index values somewhat in .
Feb 29, 2016· Yes. Kinematic chain: A kinematic chain is a group of links either joined together or arranged in a manner that permits them to move relative to one another. If the links are connected in such a way that no motion is possible, it results in a lock...

courses stressing kinematic issues, we often replace material from Chapter 4 (Robot Dynamics) with selected topics from Chapter 5 (Multifingered Hand Kinematics). We have also covered Chapters 5–8 in a ten week period at the graduate level, in a course augmented with other advanced topics in manipulation or mobile robots.
Aug 27, 1974· In a rolling mill, ... Up to the present time the safety measures adopted for preventing serious damage to the said kinematic chain consiste in making the coupling between each rolling stand and the relative drive shaft in the form of a safety coupling with shear pins. In this manner, if the predetermined torque limit is exceeded for any reason ...
The values from get L/Q/Z correction are wrong. Like I attach pics above in topic, when I double click on the Oprawka_sprint in kinematic chain, the value of L/Q/Z are correct, but the rest of machine kinematic is crushed. The problem is with the device, the correction values is very strange...
Kinematic pair. Kinematic pair is a joint of two Links (or elements) and it permit to relative motion. When the two links or element is having connected together that provide relative motion it is completed or successfully constrained is called kinematic pair. The practical example for kinematic pair. Crank and connecting rod connected.
