The option is used for going from one programmed point to the next according to a parabolic arc that passes through the two points. The third point identifying the parabola is calculated in accordance with the ISO RS-274-D norm (G06 function).
ES20/TR RTCP PROGRAMMING
In continuous 5-axis machining with a bi-rotary head, the machining paths make reference to the center of the head.A shift in the rotary axis is actually translated as a shift of the tool tip along the arc of a circle with a radius equal to the distance between this tip and the center of the head.The option is used for eliminating this curvature, which is compensated by the numerical control through movements of the linear axes.
The option is used for:
5-axis milling of programs developed with reference made to the tool center
Automatic compensation of tool length for 5-axis programs
Automatic compensation of rotary axis speeds and accelerations with respect to the tool center
5-axis execution of machining programmed for 3 axes, with manual movement of rotary axes (in jog mode or using the handwheel)
Execution of fixed cycles with any tool orientation
Tool withdrawal and re-approach along its vector, with automatic return to the detachment point
Automatic execution of a 5-axis machining program that also contains information on the direction of the normal vector to the surface at each point, with the purpose of maintaining the angle set between the tool axis and the surface itself constant
Compensation of any off-centering between the centers of rotation of the 2 rotary axes
Automatic execution of a 6-axis program on machines equipped with a bi-rotary head and continuous revolving table
