For calculating real cutting speed, use formula: Basic cutting TiAlN or AlTiN speed * Factor Basic Cutting Speed Vc m/min Choose the coefficient according to the ap/D and average wall angle. Material
Group min max
Example 1:
For Tool = 10mm and ap = 0,2mm for average wall angle 0°, ap/D ratio P3 160 – 180
equal 0,2/10 = 0,02. Factor equal 3.6.
P4 140 – 160
Example 2:
H1 100 – 140
For Tool = 8mm and ap = 0,1mm for average wall angle 10°, ap/D ratio
| equal 0,1/8 = 0,0125. Factor will be between 2.7 and 2.4, choose 2.6. | H2 | 70 | – | 120 |
| Keep in mind shank diameter and length effect. | H3 | 60 | – | 90 |
| If tool length out of the chuck is more than 2 x D, please decrease feed | H4 | 50 | – | 70 |
per tooth by 15% each 1 x D.
