3. New Functions for Programming and Operation
New Cycle 16 ORBIT
Cycle 16 ORBIT was developed from Cycle 17 with additional parameters for more functions. All
input values except the M functions can be transferred by Q parameter. Cycle 17 can therefore
completely replace Cycle 17.
Example:
CYCL DEF 16.0 ORBIT
CYCL DEF 16.1 IZ-5.02 M36
CYCL DEF 16.2 RAD=20.014 DIR=0
CYCL DEF 16.3 PAT=0 SPO=0
Input value and dialogs:
16.1: IZ-5.02
Eroding axis and depth (Q-Parameter)
16.1: M36 Miscellaneous function M
16.2: RAD=20.014 Expansion radius (Q-Parameter)
16.2: DIR=0 Orbit direction (0=CCW, 1=CW) (Q-Parameter)
16.3: PAT=0 Expansion pattern (0...5) (Q-Parameter)
16.3: SPO=0 Sparking out condition (0/1) (Q-Parameter)
PAT (=expansion pattern)
0 = Continuous widening on a circular path with simultaneous plunging in the erosion axis, gap
control on revolving oblique vector; retraction with Timing/Cycle Stop on oblique vector to the
starting point
1 = Same as 0, but with quadratic instead of circular expansion
2 = Orbital erosion with constant radius, gap control only in erosion axis, retraction with
Timing/Cycle Stop on oblique vector to the starting point
3 = Same as 2, but with quadratic instead of circular expansion
4 = Execution in 2 phases (new):
1. Erosion in radius to final radius with simultaneous erosion in erosion axis to final depth at 0
degree angle. Gap control on vector.
2. Expansion on circular path with constant final radius, gap control on the circular path, but
retraction with Timing/Cycle Stop on oblique vector to the starting point.
5 = Same as 4, but with quadratic instead of circular expansion
SPO (=sparking out condition)
0 = End sparking out if final radius has been reached and the sparking-out time (MP2110 or Cycle 4)
has expired (fast sparking out)
1 = End sparking out if final radius has been reached and there have been 1 ¼ revolutions of
continuous free-running (M2616) (complete sparking out)
