As a promising processing technique of hard and brittle materials, ultrasonic assisted grinding (UAG) can enhance the machining efficiency and improve the surface integrity [4].
Moreover, ultrasonic vibration also leads to an increase in shear stress strength, and the deformation and movement of dislocation of materials are easily caused.
Once a wheel depth of cut ap is given to the workpiece and a feed motion is provided to the worktable at a rate of Vw, the grinding wheel rotating at a speed of Vs will interfere with the workpiece to remove the work-materials.

The materials considered in the simulations had the following physical properties: Table 1 - Characteristics of the materials used in the simulations.
As you can see from Tables 3, the maximum error in relation to the heat was 4.06.These values are on average much lower and therefore generally acceptable. also because different types of materials were used in terms of conductivity, and we observed that the FEM model responded by demonstrating a high level of reliability and an error value which was almost constant.

Effect of Synthesis Process Parameters of PESA on its Scale-inhibiting Performance Xia Li1, a, Huaizhi Wu2, b and Xiansen Li3, c 1, 2, 3 Qingdao Institute of Bioenergy and Bioprocess Technology, Chinese Academy of Sciences, Qingdao 266101, Shandong, China alixia@qibebt.ac.cn, bwuhz@qibebt.ac.cn, clixs@qibebt.ac.cn Keywords: PESA; Scale-inhibiting performance; Scale inhibitor Abstract: Polyepoxy succinic acid (PESA) is a well-established green scale inhibitor.
Raw Materials: maleic acid, tartaric acid, fumaric acid (Tianjin Guangfu Chemical Research Institute), and epoxy succinic acid (ACROS ORCANICS, USA) are all chromatographically pure; maleic anhydride, sodium hydroxide, hydrogen peroxide (30 wt.%), sodium tungstate, calcium hydroxide, calcium chloride, sodium bicarbonate, sodium tetraborate decahydrate, EDTA and hydrochloric acid are all of analytical grade.
It is difficult to control the reaction process because the reaction proceeds violently together with pH and temperature fluctuations in the course of mixing the raw materials.
