17.5 MicroPulse
If in addition to MicroForm and MicroShift a surface structure change with Micro-
Pulse should be applied, then a good starting point is the input parameters from
Figure 8. Switch MP1 gives the choice between pulsing in X, Y, Z, A, B or in a
vector direction. It is recommended to begin a development with the vector pulse
(entry 5 or V). If the vector direction is selected, then the vector feed angles in
items MP5 and MP6 must be entered. If feed angles from a cutting or grinding
summary are available, then these are good starting points. Also, the traditional
vector feed in chapter 29 can be used to calculate suitable vector angles.

Because the pulse cycles are an approximate harmonic function, the points per
cycle MP2 should be entered as 3. A higher number will quickly come to the reso-
lution limit of the machine control computer and therefore is not recommended.
Pulse base amplitude MP3 and random amplitude MP4 can be entered with
0.002mm.

Depending on the results, possible changes are an X-axis pulse (MP1) instead of
a vector pulse and a change of base and random amplitudes (MP3 and MP4) as
