I've made some research on kerf width formation and cutting quality and currently Im interested in evaluation the dross formation. I would like to know the method how reseacher measure dross formation for laser cutting process?
I think that, if you want, you can correlate the height of dross with the cutting parameters. This is an geometric analysis.
In another sense you can study the microstructure and microhardness by metalographic studies.
At last, you can found additional information in the specialized book named: "Laser material processing" from W. Steen
Thank Prof, really looking onto it,
If possible , could you briefly explain on how to measure the dross formation at the cutting edge if the specimen are like the picture attached
Sorry, because I could not apprecciate the deffect in your image. In the attach file is very clear. You can measure with an optical instrument the heigth between the edge of piece and the dross heigth. Another methodology, because the pieces are like a sheet, is to use an comparador (Excuse me because I dont know the name in english). With this you can obtain always the maximun value.
Dross and burrs are material that can be eliminated from final part. This work is and additional work than influence over the cost. If you find parameters than minimize the dross, you can make a good work!!!!!
Yup Prof, secondary process will cost you interm of time and money. Thank Prof Daniel, really helps to generate my idea on measuring the dross of the materials.
