Lapping Pressure Automatically Controlling Method in High Speed Lapping

2010 International Conference on Intelligent Computation Technology and Automation, 2010
The computer control technique is used to control lapping pressure on-line in this paper. In the starting period of lapping, contacting state between the workpiece surface and lapping tool surface is not ideal case. In order to reduce the impact between the workpiece and lapping tool, in starting lapping, the lapping pressure is lower, and then ...

Analysis on Lapping and Polishing Pressure Distribution

CIRP Annals - Manufacturing Technology, 1998
Abstract In the processes of plane lapping and polishing, the pressure distribution between the workpiece and the lapping plate or the polishing pad is very important to flatness generation. This paper presents elastic contact models for plane lapping and polishing with or without guard ring.

Study on Lapping and Constant-Pressure Grinding of Single-Crystal SiC

Advanced Materials Research, 2009
Silicon carbide (SiC) single crystal has many advantages comparing with silicon single crystal, such as wide band-gap, hardness and various stable physical properties at high temperature and severe chemical environments. SiC semiconductor substrate is expected to be applied to high power devices and sensor devices in the severe environments.

Theoretical study of LaP and LaAs at high pressures

Journal of Alloys and Compounds, 2002
The present work employs the self-consistent tight binding linear muffin-tin orbital method to calculate the electronic structure and the relative stabilities of LaP and LaAs at high pressures in the rocksalt, primitive tetragonal and CsCl structures. At compressed volumes, these compounds favour the tetragonal phase over the CsCl phase, which can be ...

The pressure control technology of the active stressed lap

SPIE Proceedings, 2010
The active stressed lap polishing technology is a kind of new polishing technology that can actively deform the lap surface to become an off-axis asphere according to different lap position on mirror surface and different angle of lap. The pressure of the lap on the mirror is an important factor affecting the grinding efficiency of the optics mirror.

Fatigue and corrosion in aircraft pressure cabin lap splices

International Journal of Fatigue, 2001
Aircraft structures are susceptible to fatigue and corrosion damage, notably at joints. There may be interactions between fatigue and corrosion, especially as aircraft age. Longitudinal lap splices from several types of transport aircraft pressure cabins were disassembled and investigated for Multiple Site Damage (MSD) fatigue cracking and corrosion ...

Effect of Pressure Distribution on Energy Dissipation in a Mechanical Lap Joint

AIAA Journal, 2005
Mechanical joints, such as the bolted shear lap joint considered here, are ubiquitous in engineered structures, which realize vibration damping as well as load transfer from them. However, the prediction of the energydissipation characteristics of such joints remains a challenging problem.

Riveted Lap Joints in a Pressurized Aircraft Fuselage

2012
The contemporary transport aircraft fuselage is a skin structure supported by frames and stringers, Fig. 1.1. The skin and the stiffening elements carry the flight loads including those due to cabin pressurization. The stringers are joined by riveting, bonding or spot welding directly to the skin, as exemplified in Fig. 1.2.
