Virtual machining is the practice of using computers to simulate and model the use of machine tools for part manufacturing. Such activity replicates the behavior and errors of a real environment in virtual reality systems. This can provide useful ways to manufacture products without physical testing on the shop floor. As a result, time and cost of part production can be decreased.

The invention discloses a modeling method for judging the cutting force of an orthogonal turn-milling machining end face on the basis of boundary conditions. The method includes the five steps of firstly, establishing a tool coordinate system; secondly, dividing the tool end face into a plurality of microelements in the radial direction; thirdly, judging whether the microelements participate in cutting or not through the boundary conditions; fourthly, obtaining thickness of cuttings, and calculating the microelement cutting force on the basis of the thickness; fifthly, adding the cutting force on all the microelements participating in cutting to obtain the total cutting force. By means of the method for judging the cutting state of the microelements through a united boundary condition equation, the disadvantage that in the prior art, when the orthogonal turn-milling machining end face blade cutting force is predicted, the cutting progress needs to be divided into multiple stages to be discussed is avoided; due to the fact that the influences of jumping are taken into consideration, the prediction effect is more accurate.
