Cycle 800 - Swiveling made easy

SINUMERIK Operate - Swiveling in JOG and AUTOMATIC with CYCLE800

The Swivel CYCLE800 is a static plane transformation, which allows you on a 5-axis machine (e.g. swivel head or swivel table) to define a rotated working plane in space. In this work plane you can than program a 2D or 3D machining operation. This is also referred as 3+2 axis positioning, by means of the 2 rotary axes involved in the transformation being only positioned while the linear axes move during machining. By calling the appropriate NC functions, the cycle converts the active workpiece zero (e.g. G54) and tool offsets to refer to the rotated surface, taking into account the kinematics chain offsets on the machine, and positions the physical rotary axes (optional) normal to the programmed working plane.

Programming CYCLE800

You can program the tilting axes of the machine (A,B,C) or specify the rotation around the geometry axes (X,Y,Z) of the active workpiece coordinate system. The rotation of the coordinate system or the tilting angles in the program are then automatically converted into the rotation of the respective tilting axes (actual rotary axes) of the machine when machining the workpiece. The previously set zero point is also automatically converted to the new machining plane. The programmed movements of the linear axes then refer to these machining planes. The tilting axes are always machined so that the working plane is perpendicular to the tool axis. During machining, the working plane is then fixed.
