Abstract: Both
experiment and simulation are made on the AIMg4.5Mn0.4 sheet
blanking with 1%, 10% and 20% relative clearance respectively.
The cutting force curves and the cutting surface parameters
which can be used to describe the quality of the blankings are
measured. Simulation is accomplished by MARC Autoforge software
package. Calculated cutting forces are always bigger than
measured ones. All difference between experiment and simulation
is not greater than 20%.It is feasible making virtual experiment
on workstation to estimate the cutting force and to predict the
quality of the workpiece for new material using certain blanking
technical parameters.
