local convexity analysis – a powerful new tool for understanding the “bumps” that cause “stresses”. For example, this profile has a “bump” on the left side. In some applications, bumps such as these can cause major product failures. Traditional waviness parameters like “Wt” would not detect this bump as it falls inside the total peak-to-valley range of the profile. chrome steel standards of different countries for cylindrical rollers china (GCr15), USA (SAE52100,AISI52100), Germany (100Cr6), JIS SUJ-2
