Technologies for Getting Good Corners
In general, you would get bad quality when cutting sharp corners on thin materials in high speed, and on
thick materials in low speed, especially on mild steel with O
as the assist gas because too much heat

accumulated up there in a very small area which results in over burnt.
CypCut provides several functions to solve this problem from different points of view. If the geometry of a
corner has to be kept precisely, you can use the cooling point or the ring cut functions; otherwise, you can use
the fillet function, and incorporate the relief function if the part is prepared for bending.
Cooling Point
The cooling point function is to add stops in the cutting process and let the assist gas help cool the material
down a little more.
Select the contours and then select the command Auto Cooling Point in the pulldown-menu
Home>Cooling Point.
In the pop-up dialog, check the option Add at leadin if you want to set a cooling point at the start position,
check the option Add at corner if you want to set cooling points at sharp corners and set the angle range in
the option Max angle.
Cooling points appear as small circles when the contours are selected, and as solid ones when not.
