Using SSV (Spindle Speed Variance)
Spindle Speed Variation (SSV) allows you to modify the spindle speed within a range causing it to
continuously change. This changes the harmonic frequency of the machining, which can help in the
appearance of chatter. Various issues can cause chatter: spindle speed, incorrect feeds, depth of cut, part
rigidity, the type of part being machined, thin walls, or diameter-length ratio.
Checking enable SSV- will engage it for the machining process you are doing
Time per Cycle- each cycle is measured as a second.
RPM Variation- How much the rpm can vary up and down from what you set in the program
(NOTE: setting this too extreme can cause Spindle errors and spindle crashes.)
Setting Spindle Index
Any time the machine has been turned off the spindle index position must be set. Turn the spindle to
the index position (tool holder facing to the right at 90 degrees from the operator). Then press the Zero
button net to the spindle position read out. This will put a zero value in the display box.
This screen also shows the Spindle Load, programmed Feed Rate and Spindle RPM.
Probe Auto Center
The Probe is an option on the F103/4/5A machine. When this button is pressed a single Probing routine
will be run in the position the machine is currently at.
