Application of system-error-removing technology to closed

Accuracy of the workpiece ground is to be judged by measuring machine sends signals to in-process measuring instrument or grinder in order to control the feeding amount of tool thus a close-loop control system for grinding operation is formed. All errors made by the system (because of temperature humidity air pressure vibration time drift)will be removed through calibration with standard workpiece (self-examination of the measuring machine). FOREWORD With the development of science and

Optimizing the control system of cement milling: process

In the cement industry, a heavy industry absorbing extremely high energy, the automatic control of the grinding process remains a challenging issue, due to the elevated degree of uncertainties, process non-linearity and frequent change of the set points and the respective model parameters during operation. For productivity and quality reasons, grinding is mostly performed in closed circuits: The ball cement mill (CM) is fed with materials. The milled product is fed via a recycle elevator

Intelligent and Integrated Gear Grinding Workflow : Gear

The direct connection between the grinding and measuring machines is known as “closed loop“ within the sector. The measuring machine provides data not only in form of reports, but also as GDE dataset. In the first version, these are the typical correction variables (fHα, fHß, tangent length correction /pitch correction) which will change in case of a temperature increase or tool wear. Compared to manual input, these data can be imported and analysed much quicker and with fewer errors

Intelligent grinding tool | IPH

The objective of this work is to investigate a closed loop control for an abrasive cutting process using thin cutting discs. The used diamond cutting disc is 40% thinner than normally used tools in the industry. For the implementation of a closed loop control a monitoring system is being developed. It allows monitoring the axial tool vibrations throughout the grinding process. Integrating piezoelectric elements in the grinding tool, the vibrations can be detected directly at their source

Modeling and control of cement grinding processes | Semantic › paper › Modeling-andIn this study, a nonlinear dynamic model of a cement grinding process, including a ball mill and an air separator in closed loop, is developed. This gray-box model consists of a set of algebraic and partial differential equations containing a set of unknown parameters. The selection of a model parametrization, the design of experiments, the estimation of unknown parameters from experimental data, and the model validation are discussed. Based on the resulting model, a dynamic simulator can be

Closed-loop force control for a semi-automatic grinding system › paper › Closed-loop-forceAs an approach to the automating grinding process, a gantrydriven grinding machine is proposed to manipulate an industrial hand grinder and control the grinding force applied to the work piece. To increase the material removal rate of the grinding machine, a grinding force control method is brought forward. This method suggests that the normal grinding force should be controlled to a desired constant value. A double closed-loop grinding force control system is designed to perform the

Intelligent systems for induction hardening processes. Final

Current limitations of the process include the lack of closed-loop process control, previously unidentified process and material variations which cause continual adjustment of the process parameters, coil and process development by trial and error, and an instability to monitor coil condition. Improvement of the induction hardening process is limited by an inadequate understanding of process fundamentals and material/process interactions. A multidisciplinary team from Sandia National
