General machine parameters
Meaning of the parameters in the TC work mode.
LOOKATYP (P160)
This parameter has 16 bits to configure the operation in G51 for high speed machining with look-
ahead.
There are 3 operating modes for G51: advanced algorithm, jerk control algorithm and standard
algorithm. The algorithm is selected using general machine parameter LOOKATYP (P160).
1. Advanced algorithm: use bit 15 of general parameter LOOKATYP (P160) to activate it.
Recommended for small and rigid machines, especially for the engraving sector.
When using this algorithm, machining speed is more important than machining accuracy. If the
machine is not rigid enough, it may be rather jerky and, consequently, it is recommended to use
it together with the machining smoothing option (bit 14).
Plus, it is also recommended to activate bit 12 for speed control in arcs made up of linear blocks,
especially for accurately machining small radius arcs made up of small linear blocks.
By default, general parameter LOOKATYP (P160) takes the value of: 1101 0000 0000 0000, i.e.
advanced algorithm with smoothing and speed control in arcs made up of small blocks.
