The aim of the presented monograph is to summarize current theoretical knowledge about theory mechanoscopy, theoretical knowledge of the mechanism of origin and extinction mechanoscopic traces and to evaluate the current state of methods of providing and exploring mechanical tracks. Emphasis is placed on the area of theory mechanoscopy. The paper evaluates current criminal methods and procedures experts in the development of expert opinions in the field of mechanoscopy. Here there is a time comparison that compares the current situation with the past. Next work examines new projects, methods, and trends in the field of expert exploration are currently running. We used a range of professional publications in the process mechanoscopy.
