Author contribution statement
HM conducted the PJP experiments and measurements, performed analysis of the results and handled the paper documentation. SH and CS conducted the grinding experiments and measurements, SH was also mainly responsible for the evaluation of the research and the writing of the paper for this part. SF contributed the design and construction of the Alvarez geometry. JB contributed significantly to the evaluation and interpretation of the results with his expertise in the field of manufacturing technologies, and corrected and expanded the manuscript. TA wrote MATLAB fitting routines, offered valuable advice for the interpretation of PJP data and took extensive care of correction of the manuscript to present the data more clearly. The authors have read and approved the final manuscript.
