Relationship between the radius of the hottest tip

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


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