Bonding force between two slip guages will be inflenced by surface finish,material,wrining effect etc., what is the relationship between all ? Anyone knows how to calculate theoretically?

The wringing effect in slip gauges occurs due to the intermolecular forces between the flat surfaces of the gauge and the reference surface. These forces, known as van der Waals forces, create a strong bond between the two surfaces, allowing them to stick together.
The bonding force in slip gauges is affected by several factors including the materials and surface roughness of the gauge and reference surface, the contact area between the two surfaces, and the environmental conditions such as temperature and humidity.
The bonding force in slip gauges can be calculated using the equation F = σA, where F is the bonding force, σ is the surface energy of the materials, and A is the contact area between the two surfaces. The surface energy can be determined experimentally or through theoretical calculations.
Calculating the bonding force in slip gauges is important for ensuring accurate measurements. If the bonding force is too strong, it may cause the gauge and reference surface to stick together, leading to errors in measurements. On the other hand, if the bonding force is too weak, the gauge may slip, also causing measurement errors.
Yes, there are several methods to reduce the bonding force in slip gauges such as using special coatings on the surfaces, minimizing the contact area between the two surfaces, and controlling the environmental conditions. Additionally, using a gentle twisting motion while removing the gauge can also help reduce the bonding force.
