19.3.2 Explanation of the Input Parameters
Pitch value
Input Range: 0 – 100 mm
This is the axial pitch of the thread to be ground.
Number of Starts
Input Range: 1 - 12
This is the number of threads or starts to be ground on the workpiece
Thread Sense
Input selection: LH or RH
If the workpiece has a left-hand thread then select LH
If the workpiece has a right-hand thread then select RH
Press the blue [Select] key on the HMI panel to toggle between LH or RH thread.
Taper (dia)
Input range: 0 – 0.5 mm/mm
Amount of taper required on the workpiece.
Minor Diameter
Input range: 5 – 100 mm
Root or minor diameter of the workpiece thread.
This is the final diameter at which workpiece thread grinding will stop. When establishing the minor
diameter value, check the diameters of all of the components in the batch to be ground before you
begin to run any setup cycles. Usually there will be some variation in start diameters so you should
determine which component in the batch has the smallest minor diameter.
Profile
Name of the dress profile program that you want to use.
Note: This only applies when the PMHMI flag is OFF.
If you are using a diamond disc then enter the name of the dress profile program that you created
with the Ball Profile software which has already been copied and loaded to the Sub-Programs folder
in the PCU50. Leave this field blank if you are using a diamond roll.
