If you want to find out the time history of a variable, you can insert Body or Point Results Trackers under Solution Information to get it. For example, you can get the time history of the contact force on the cutting tool or reaction force on the specified axis using Body Results Trackers -> Contact Force or Force Reaction. Please be aware that results trackers can only be inserted before you are solving the model. Once solution is obtained, you are not able to insert the results trackers.
