Study of thresholds to burning in surface grinding process

ABSTRACT. This work aims at finding out the threshold to burning in surface grinding process. Acoustic emission and electric power signals are acquired from an analog-digital converter and processed through algorithms in order to generate a control signal to inform the operator or interrupt the process in the case of burning occurrence.

One of the most common types of thermal damages in grinding process is the burning of the part. When the superficial burning of the part is initiated, there is a trend of growth of metallic particle adhesion in the abrasive grains of the grinding wheel, having as consequence the increase of the grinding forces.

Grinding burn - Preventing and Monitoring! – grindaix

The term grinding burn while grinding is understood as the thermal damage of a ground part caused by an incorrect grinding process. Grinding burn is caused by excessive heat dissipation into the part material. As materials cool as rapidly as they heat, the material undergoes a treatment similar to a tempering process.

Grinding Burn | SpringerLink

May 26, 2018 · Grinding burn is defining an upper limit for the desired grinding operation as it does heavily depend on the process parameters like cutting speed, feed rate, and coolant supply as well as the used tool and dressing conditions. Damage due to grinding burn destroys the whole value creation accumulated so far.

Grinding burn is progressive and will initially result in cracking. These cracks may appear immediately after the grinding process, or arise later from residual stress concentrations. Regardless, once initiated these cracks tend to propagate rapidly to macropitting and tooth fracture. If identified, grinding burn is cause for serious concern.
