It can be difficult to define application area just by looking at a drawing
It isn´t just the level of interruptions that’s defining an application area. It´s many other process factors that will affect the choice of PCBN grade. A drawing on the finished part explains just the properties of the component. Factors like Machine tool, clamping, workpiece stability, variations from the green turning, workpiece stability, etc. are factors that actually can “move” an application from what on the drawing looks like a H05 application to a H15 and in some extreme cases from H05 to H25.
Example: Large variation from the green turning on a Pinion “moved” the application from what on the drawing looked as a H05 to in the reality a H25 application. (From CH0550 to CH2540)
