Experimental study on the influence of lapping plate materials on the quality of both sides cylindrical rollers machining [PDF]

Scientific Reports
The both-sides machining method can obtain high precision cylindrical rollers, but there is a drawback that the lapping plate is easy to wear, which restricts further improvement in the quality of rollers machining.

Behaviour of bolted lap joints in above-ground liquid-filled steel cylindrical tanks [PDF]

Canadian Journal of Civil Engineering, 2022
Leakage is the main concern in steel bolted liquid tanks and past experience has indicated serviceability problems due to leakage, mainly from the joint locations, even in situations where the tank has only been subjected to an internal hydrostatic pressure.

Development of the Lap for Correcting Cylindrical Axes

Journal of the Japan Society of Precision Engineering, 1979
The lapping has been used experientially for finishing method for higher roundness of cylindrical axes. But, there are very few reports about the principle of the finishing method. This report presents the characteristics of the changing process of the cylindrical forms and the characteristics of the combinations between the workpiece and lap.
