The article describes a new technology in milling of the flat surfaces - Inverse Cutting Technology. The theoretical basics of the inverse cutting are formulated. The boundary conditions of the process depending on the cutting parameters are presented. The chip formation and chip flow by inverse milling are simulated. The comparison of cutting forces by conventional and inverse face milling is shown. Finally, cutting experiments were conducted to confirm the results of the 3D-FEM-simulation.

It is well established that in metal removal processes almost all the energy used for the process is transformed into heat, thus affecting the tool life and the accuracy of the workpiece. The primary heat source is the deformation work and friction in the contact zone between the workpiece and the tool, which cause the temperature to increase. In order to control the temperature increase, cutting fluids are used to reduce friction and to remove the heat from the work zone. A finite element method based computer model was developed for the simulation of thermal deformation in multipass turning when different cooling conditions were applied. This paper presents novel theoretical and experimental solutions to establish model parameters in order to ensure adequacy of the model to the real heat transfer process in turning. This new inverse problem solution (IPS) technique was applied to obtain the heat generated by the cutting process and the heat transfer coefficients from the workpiece to still air and the air-oil or air-water cooling mixture. The predicted results for workpiece temperature field and workpiece accuracy are in good agreement with the measured data.
