Laserhardening - example: cutting tool

Following example shows our mobile laser hardening machine during hardening of a cutting tool.
The challenging geometrical changes (concave and convex) are beeing controlled by our laserpower control to guaranty a nearly constant surface temperature.
Heat accumulations caused by holes in the tool are also avoided.

The diagram next shows the surface temperature and the controlled laser power.

Clearly to recognize is the laser power descent at the first edge of the tool.
Due to the heat accumulation at the outer edge of the tool the laser power has to be decreased to avoid a melting of the surface.
The laser power control results in a nearly constant surface temperature range of +-5K.

Therefore at inner edges is the need for more laser power while more material has to be heated up.
Also here using the laser power control results in a nearly constant surface temperature range of +-10K.
