20/03/2019· Grinding is an important machining method, and the quality of the workpiece is determined by the precision of the grinding process. 1 In recent years, due to the development of industrial intelligence and automation, the demands for real-time measurement devices and process control instruments for the grinding process are increasing tremendously. 2,3 The cylindrical grinding
A grinding wheel is an expendable wheel used for various grinding and abrasive machining operations. It is generally made from a matrix of coarse abrasive particles pressed and bonded together to form a solid, circular shape, various profiles and cross sections
Barkhausen Noise: A Method for Checking Grinding Quality An effective method for grinding process control and quality inspection is the Barkhausen Noise method. This method was first discovered in 1919 and implemented to grinding quality control during the 1980s. It is sensitive to residual stresses and microstructure, which are directly
The mechanical dressing method is currently the most widely used grinding wheel dressing method, which includes turning, rolling and grinding method [,,]. Turning and rolling methods are mostly used for the dressing of ordinary abrasive wheel. Grinding method is to dress the grinding wheel by the grinding action caused by the relative
Use wet methods rather than dry when drilling or grinding. "Wet method" means that water is sprayed over a dusty surface to keep dust levels down or material is mixed with water to prevent dust from being created. Use an appropriate vacuum or "wet method" instead of dry sweeping (e.g. with a broom) to control dust and reduce the inhalation hazard.
The optimization method aims to smoothen the trajectories of the control parameters of the robot and shorten the response time in the transition process. The results of the blade grinding experiments demonstrate that this approach can control the material removal of the grinding system effectively.
The article "Twist Control Grinding" appeared in the June 2017 issue of Gear Technology. Summary This paper introduces the latest process developments for the hard-finishing of gears, specifically in regard to controlling the so-called flank twist. Keywords grinding, twist control, grinding twist, Reishauer, generating grinding, bias
In this paper, a method of hybrid force-position control combined with PI/PD control is applied in an actual robotic belt grinding process. Most importantly, the process grinding force can be remained constant relatively, and the depth of grinding (namely, the Z offset) can also be set as a fixed value in theory. In Fig. 5, the grinding force is changed into the reference force adaptively with
One of the most effective ways to do so is capturing the concrete dust at the source before it spreads into the air. Also, there are environmental regulations in place to prevent dust emissions or to control their contamination using the best possible means. 2. Wet control methods
Ideal hydrocyclone control is constant pressure, feed density, and flow rate. These three things are difficult to control in the real world which is why people settle for poor hydrocyclone performance by doing sump level control. Achieving the best combination of pressure, density, and flow requires an advanced control system like MPC or similar.
A new control method is proposed for an improvement in grinding efficiency and is described as the optimum size and roundness adaptive control method. An accurate description of the control actions is provided, and the adaptive algorithm used by the proposed method also enables a low-cost computer system to be used. A case study of the grinding
This control should not be considered a grinding control but should be used by the operator to control the particle size of the cyclone overflow. Another control the grinding operator can often employ is the number of cyclones in the circuit. By increasing or decreasing the number of cyclones in the circuit the operator can influence the
The cylindrical grinder is a type of grinding machine used to shape the outside of an object. The cylindrical grinder can work on a variety of shapes, however the object must have a central axis of rotation. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft.

The nital etching and micro-hardness methods can only detect severe grinding damages. Furthermore, both methods have the same challenges: traceability and repeatability. XRD method can also be used to detect the grinding damages. However, it is time consuming, expensive, and destructive when subsurface stresses need to be analysed.
