Intermittent grinding temperature modeling for grinding system state monitoring

Applied Aspects of Information Technology, 2020
A dry and wet intermittent grinding temperature mathematical model for the thermal macro- or micro-cycle was developed and studied. The heating stage corresponds to the wheel cutting segment passage time through the every contact zone point.

POSSIBLE WAYS TO REDUCE THE COST OF GRINDING PROCESS OF PRODUCTS WITH INTERMITTENT CIRCLES [PDF]

Odes’kyi Politechnichnyi Universytet Pratsi, 2018
Grinding in most cases is the final operation of machining, on which the quality of the surface layer of the manu-factured part is formed. Stable quality of the surface layer during grinding and high productivity can be ensured by using grinding wheels with a discontinuous working surface.

Calculating the profile of intermittent grinding wheel for the sharpening teeth of the broach [PDF]

MATEC Web of Conferences, 2018
The article shows that during the grinding of complex profile blades of metal cutting tools from tool steels, unfavorable thermodynamic conditions are created in the cutting zone and, as a result, grinding burns and cracks occur on the surface of the polished workpiece.

Features of intermittent profile grinding cylindrical gears

Izvestiya MGTU MAMI, 2013
The conditions of engagement of grinding wheel with teeth of the cylindrical wheel when intermittent profile grinding are considered in the paper. There are investigated the possibilities of reducing the thermal stress of the grinding process by means of use of highly-porous abrasive wheels, limitation of specific speed of metal removal and sector ...

RESEARCH OF DYNAMIC PHENOMENA OCCURRING DURING INTERMITTENT GRINDING

Cutting & Tools in Technological System, 2019
Применение шлифовальных кругов на поверхностях, которых имеются прорези, позволяет снизить тепловыделение в зоне резания. Целью научного исследования является определение условий создания в упругой системе станка колебаний, способствующих самозаточке режущего микрорельефа прерывистого круга, и возникновения ударного и параметрического резонансов ...

Simulation of thermal strength of the process of flat grinding of workpieces in intermittent circles [PDF]

MATEC Web of Conferences, 2019
The present article is concerned with numerical schemes of the radial Py and the tangential Pz components of the grinding pressure and with the average contact temperature T, °С. These characteristics give an opportunity to assess the level of the thermal power strain at every path of the operational cycle of the flat pendulum grinding using a standard

INVESTIGATION OF RESIDUAL STRESSES DURING FLAT GRINDING WITH AN INTERMITTENT ABRASIVE WHEEL

Izvestiya of Samara Scientific Center of the Russian Academy of Sciences, 2023
A technique for investigating residual stresses during flat grinding with an intermittent abrasive wheel is given. As a result of the study, it was found that tangential residual tensile stresses are formed in the direction of the cutting speed. Axial residual compression stresses are formed in the direction perpendicular to the cutting speed.

Experimental Study and Numerical Simulation of the Intermittent Feed High-Speed Grinding of TC4 Titanium Alloy [PDF]

Metals, 2019
This paper proposes intermittent feed high-speed grinding, which shows considerable advantages in terms of reducing grinding temperature, relieving grinding wheel blockage and improving workpiece surface integrity. In this grinding, the continuous feed mode of the workpiece is changed into the normal feed + fast retreat reciprocating feed mode by a ...

REFINED CALCULATION OF CUTTING TEMPERATURE DURING INTERMITTENT GRINDING

Bulletin of the National technical university "Kharkiv Polytechnic Institute" Series: Techniques in a machine industry
A mathematical model for determining the cutting temperature during intermittent grinding has been developed and the conditions for its reduction have been substantiated, taking into account the balance of heat released during grinding and supplied to the chips and the workpiece.
