Summary
The aim of the course is to acquaint students with theoretical and experimental ways of describing typical features left by the traces of flexible jets on the material, ways of compensating and simulating these compensations. The main benefit should be to familiarize students with the negative features of working with flexible tools, to learn how to predict their size according to the type of material, its dimensions, the speed of material processing and other factors. The student should learn whether a theoretical or experimental approach is appropriate to solve the problem, whether the necessary precision can be achieved by the use of compensation, or whether the flexible tool is inappropriate in application due to the impossibility of executing the required precision, enormous costs, environmental damage, etc.
