RSM Range:

Radii*: 0,50mm - 5,00mm
Z*: 6, 8 & 10
* Radii and Cutting edges
dependent on diameter
RSM AEROSPACE PROGRAM
The RSM program is specially designed to overcome a number of problems usually
associated with machining Titanium components, in particular the proling of walls, pockets
and surfaces in 2D and 3D applications.
Issues such as vibration and material tarnishing are signicantly reduced by the tool’s unique
geometry. The tool also features a reduced shank which offers optimum exibility. This allows
the user to obtain maximum reach and workholding length* to suit individual requirements,
thereby reducing required inventory.
* Recommended minimum secure clamping length is 2,5 x shank diameter.

When using a

/ a

= 15,5 / 1

In the application of RSM end mills, it is vital that a

Solid Carbide End Mills
Technical Information — RSM
In the application of RSM end mills, it is vital that ad max mm
2
is not exceeded, for this, adjust a
e
& a
p
accordingly.
Key:
a
e
Radial depth of cut (mm)
a
p
Axial depth of cut (mm)
a
d
Cutting section (mm
2
)
f
z
Feed per tooth (mm/z)
h
m
Effective chip thickness (mm)
Example based on values for RSM250 (Z=10)
Example:
When using a
p
max, then a
e
= ad max mm
2
/ a
p
max
= 15.50 / 32.50
= 0.47mm
When using a
e
(max), Then a
p
= ad max mm
2
/ a
e
max
= 15.5 / 1
= 15.50mm
When the length to diameter (Lu:D) exceeds 3:1 the speed
(V
c
) should be reduced as per the following graph.
Cutting Section (a
d
) and Speed (Vc) Correction Coefficients
When the length to diameter (Lu:D) exceeds 3:1 the cutting
