Numerical control five axis machining is an advanced machining technology that can accurately process complex geometric shapes, especially free-form surfaces. Haec methodo machinationis prima relinquetur super quinque parte machinationis ad axis, quod in quinque gradus libertatis positum est et connectabitur, inclusive tres axes moventes (x, y, z) et duas axes rotantes. Specifically, CNC five axis machining has the following advantages: 1, improved machining efficiency: As five axis machining can complete the machining of multiple surfaces in one clamping, it reduces the number of clamping times and auxiliary time, and improves machining efficiency. 2. Reduce difficultatem machinarum: For complex surfaces and cavities that are difficult to complete with three-axis machining, five axis machining can be easily accomplished. 3. Improve machining precision: Five axis machining has high positioning accuracy, which can ensure the geometric shape accuracy and surface roughness of the machining. 4. Valde applicabile: quinque machina asses ad diversas industrias, sicut aviatio, aerospace, automotiva, molda, etc.
