Abstract:
Tools of grade N35/3 and N35/RD25 were tested to .030 in. flankwear
at cutting speeds of 500 fpm with 0.010 in/rev feed and 250 fpm. with
0.010 in/rev feed and 0.030 in/rev feed machining EN 9. The results
showed that N35/3 gave the better performance at the higher cutting speed
and that the two grades gave the same performance at the lower speed.
At 250 fpm and 0.010 in/rev feed the wear of both grades was mostly
confined to a groove at the depth of cut. With the larger feed both
grades of tool suffered severe deformation of the cutting edge.
