9.12 CUTS AT EXTERNAL ANGLES OF LESS THAN 30° - SPECIFIC RULES
For angled cuts below 20°, the quality of cut is considerably compromised by: cutting speed, blade quality,
position of the vices. It is therefore recommended that the following sequence of operations be performed for
this type of cut:
- Reduce the blade exit speed to the minimum since, at these angles, the blade has to cut a large profile surface
area.
- Make sure the blade is correctly lubricated.
- Use optimum clamping; for profiles that are not flat special jaws should be used.
- Use quality blades that have a very rigid body because during re-entry after cutting any blade heeling will ruin
the piece cut.

In general, for any cutting angle, it is best to use all the vices available on the machine, especially for cuts at
large external angles below 30° (see Fig. 09-24).
