Research on Process Planning Method of NC Tube Bending

In order to improve efficiency and quality of tube process, a new process planning method for NC tub bending is proposed. Factors affecting NC tube bending process is firstly discussed, and NC bending process planning is also achieved by theoretical process set calculation, occurrence of interference processes set analysis, clamping difficult process analysis and optimal set of processes selection. The method above is effective and useful for planning process of the complex tube bending parts.
