Gas Turbine Cylinder Nc Milling Tilt Hole Parametric Programming
In machining, it often encounters milling large inclined holes with spindle on unvertical space. On 3 axis coordinated NC boring-milling machine, universal Angular milling head for changing spindle direction is adopted to align hole axis with milling cutter axis, using geometrical space establishes mathematical model between each processing variables to realize NC program parameterization of space inclined hole milling. Results show that the work piece only need chucking once, give the relevant variable values, can be completed holes, processing high accuracy, saving labor and power, and it also can be extended to machine similar space bevel surface and tilt slot.
