OSAI OPENcontrol - Tool Radius Compensation; Motion Modality (accel and decel RAMP parameters); Point to Point and Continuous Mode with Look Ahead

Tool Radius Compensation
OPENcontrol automatically applies the tool radius compensation calculating the axes
trajectory needed for machining the path described in the part program. This functionality
(enabled by G41, G42 codes) can be instructed to compensate either the tool radius or
the tool thickness. The Tool Compensation can also be applied in the space (3D) either
through the Paraxial Compensation (compensation factors u,v,w) or through versors
(m,n,o and p,q,d) when TCP (Tool Center Point) is active.

compensations through versors.
Motion Modality (accel and decel RAMP parameters)
OPENcontrol makes a sophisticated interpolation algorithm available that controls the
axes acceleration/deceleration phases on the basis of the dynamic requirements of
the machine. Acceleration and deceleration are also independent and can be set with
different parameters. OPENcontrol manages:

Linear Ramp

S Ramp

Trapezoidal Ramp

S Ramp with Jerk limitation
Point to Point and Continuous Mode with Look Ahead
In point to point mode (G29) OPENcontrol executes the programmed movements stopping the
axes at the end of each move. In continuous mode (G28) the system executes all movements
at the programmed feedrate, without stopping the axes at the end of each move.
The G28 continuous movement follows the prole at high speed, but can cause overshoots
on the edges or during inversion of the axes. For this reason another type of continuous
motion (G27) is available. It “foresees” the dynamics of the motion of the axes along
the path (up to 1024 Look Ahead blocks) and adapts the speed of the tool accordingly, so
that the output velocity from the individual blocks dening the trajectory is optimized.
The narrower the angle between two successive blocks is, the more the speed is reduced,
going to zero if a preset threshold is exceeded.
OPENcontrol has new automatic high performance algorithms for determining the speed
of the axes in the transition from one block to the next in G27 mode.
