A Study on Electrolytic In-Process Dressing (ELID ...

Single crystal sapphire is of significant interest due to its combination of excellent optical, electrical, and mechanical properties. However, fine grinding of sapphire is quite challenging because of its high hardness and low fracture toughness, making it sensitive to cracking. Wheel loading is a common problem in conventional grinding of hard and brittle materials. ELID grinding shows great ...

Optimization of Single-Sided Lapping Kinematics Based on ...

The chapter presents the influence of selected kinematic parameters on the geometrical results of the single-sided lapping process. The optimization of these parameters is aimed at improving the quality and flatness of the machined surfaces. The uniformity of tool wear was assumed as main optimization criterion. Lapping plate wear model was created and in detail was analyzed.

Tool Wear Prediction in Single-Sided Lapping Process

Single-sided lapping is one of the most effective planarization technologies. The process has relatively complex kinematics and it is determined by a number of inputs parameters. It has been noted that prediction of the tool wear during the process is critical for product quality control. To determine the profile wear of the lapping plate, a computer model which simulates abrasive grains ...

Sometimes, single side grinding is preferable over surface grinding, because it has the ability to produce flat surfaces. However, the manufacturing cost is still high because of the high tool wear and long machining time. Additionally, most of these grinding processes are followed by a lapping process.

Microgrinding of flat surfaces on single-disc lapping ...

Some technologies possess the advantages of both lapping and grinding. ELID-lap grinding has the advantage of using micrograin-wheels above #10000 and can be used on existing lap machines (Itoh et al., 1998). Simultaneous double side grinding (SDSG) is believed to be as effective as lapping in waviness reduction (Li et al., 2006).
