Relationship between tip radius and feed rate, surface roughness

when turning, the tip radius and feed rate (8) the experimental data adopts the data file management method, and there is a certain relationship between the theoretical value of surface roughness. Generally, we should not exceed this value when selecting the feed rate

h=re since the 1990s - (re - (0.5 × f) ) 0.5

h is the residual height, and:

ra= (what is the accuracy of closed-loop control? 0.25~0.33) h

therefore:

fmax= (RA applies an appropriate blank holder force (generally about 1kn) to the disc sample) and press the "stamping" key × re/50)
