This work presents a research on the static structure and modal analysis of precision grinding machine bed. The solid model is created with 3D design software SOLIDWORKS and analyzed by FEA software ANSYS. In order to alleviate the influence of deformation and vibration on precision grinding machine bed, some factors that can influence mass, max displacement and model frequency ware are analyzed.
The grinding test is used to study the vibration of the processing system or the grinding machine. At the same time, the grinding process can be controlled by changing the process parameters that have an impact on the grinding process (such as the amount of grinding), thereby limiting the generation of vibration.
The careful selection of exposed and control groups for analysis strengthens the observed association between vibration syndrome and the occupational use of pneumatic chipping hammers and grinding tools. In the foundry populations studied the vibration syndrome was severe, with short latencies and high prevalences of the advanced stages.

1. Introduction. The CNC vertical milling machine is a very important machine tool in the equipment manufacturing industry, which can process parts with complex shapes in batches with high machining accuracy and high efficiency , , .With the increasing requirements for product quality and high speed machining, it is urgent to improve the processing accuracy and performance of CNC vertical.
Most situations bearing vibration cannot be measured directly and so the bearing vibration signature is modified by the machine structure and this situation is further complicated by vibration from other equipment on the machine i.e. electric motors, gears, belts,.
Feb 24, 2014 High radial vibration levels on the coupling end of a machine or high axial vibration levels at the thrust end of machine are both excellent indications of alignment issues, he explains. “Vibration issues related to alignment normally show up at.
The vibrations from the machine tool not only affect the quality of the machined part but also the machine tool itself, since the cutting tool is susceptible to break or wear quickly when operating at high vibration modes, thus inevitably decreasing tool life. Vibration control has gained considerable attention in many areas including aerospace,.
Abstract The paper describes theoretical analysis of dynamics of system machine–tool–workpiece for cylindrical plunge grinding. The functional as well as mathematical model of grinder equipped with hydrostatic bearing of grinding wheel spindle and hydrostatic slideways has been presented in the paper. Simulations based on that model allow qualitative investigation of grinding force.
This research thesis aims to achieve the structural analysis and active vibration damping of the Tetraform machining structure. The Tetraform is a space frame made up of four equilateral triangles with spherical masses at the four vertices. This frame was originally developed for grinding of optical lenses and is now being adapted for use in micro-precision milling.
Measuring machines where vibrations must be kept within acceptable limits to achieve the desired surface finish, tolerances or accuracies. Depending on the circumstances, it should be noted that a machine could be both a source and recipient of unwanted vibration. For example, a surface grinder is generally a vibration-sensitive piece of.
Unwanted vibration in machine tools like milling, lathe, grinding machine is one of the main problem as it affects the quality of the machined parts, tool life and noise during machining operation. Hence these unwanted vibrations are needed to be suppressed or damped out while machining. Therefore the present work concentrates and aims on study of different controllable parameter that affect.
FE Analysis of a grinding machine The mechanical behavior of a grinding machine depends to a great extent on the vibration behavior of single components, selected assemblies and the entire machine. The presence of critical eigenfrequencies and modes inside the rotational speed range of the spindle must be avoided to guarantee the precision of.
Aug 01, 2007 To evaluate the reduction in the vibration level of the centerless grinding machine due to the action of the controller, the four different machining conditions shown in Table 1 were programmed and two workpieces were machined in each setup condition, the first one with no control applied and the second one with control applied.
Process control systems for grinding machines. The balancing of the spindle and grinding wheel is an essential operation in order to achieve the machining’s surface quality and to ensure a long life of the rotary components.
