A micro-grinding approach is proposed to fabricate micro-groove array on tool rake surface. These micro-grooves were used to rapidly dissipate cutting chips and heat from cutting zone for eco-cutting of titanium alloy without any coolant. This tool is called micro-grooved tool. The objective is to replace chemical and high-energy-beam etching approaches because they have not yet been able to ...

Due to the small feed rate used in micro-machining, ploughing force needs to be considered in addition to the chip formation force. A new analytical model has been proposed to calculate cutting forces of micro-grinding process based on the process configuration, work piece material properties, and micro-grinding tool topography. The proposed approach allows the calculation of cutting force ...

4th Axis Milling CNC Precision Milling. This cutting includes the above axes plus one rotary axis movement. There are two possibilities - 4 axis simultaneous interpolation (also known as true 4th axis) or just 4th axis positioning, where the 4th axis can reposition the part between 3 axis operations, but does not actually move during the machining.
