The ADF Control is a single axis CNC control that will automatically index the grinding wheel down during the grinding cycle. There are two different programs available on the ADF. The first program is the index program in which the machine operator enters the desired program values and runs a cycle that indexes the grinding wheel down based on the selection of either the table or saddle proximity switches. The selection of the proximity switch allows the index program to either be used for slot or surface grinding.

The index program uses the following parameters:
RAPID DISTANCE - ROUGH INCREMENTS
ROUGH DISTANCE - FINE INCREMENTS
TOTAL DISTANCE
SPARKOUTS
RETURN HOME

The following are also controls of the Index Program:
FEEDRATE
DWELL
WEAR COMP
REPEATS

1. If the ADF control is in the auto mode, pressing F1-cycle will cause the table and/or saddle to cycle until the appropriate dog activates the program selected proximity switch. If a dog already activates the proximity switch, the program goes to Step 2 without cycling the table/saddle into position.

2. The grinding wheel goes to the program zero or home value if it is not already there.

The second program of the ADF is a basic plunge program. The control feeds the grinding wheel to a specified depth at a programmed feedrate. The plunge program does not require any proximity switches to operate. The setup page is similar to that of the index program.

From the zero, or home position, the wheel will go down high speed at the rapid value, and it will hold its position for one second and begin to feed down the total distance at the programmed feedrate. At the total distance the wheel will remain at the programmed dwell amount timed in seconds, at which the wheel will go to the home position at rapid velocity.

The ADF Index Cycle Operates as Follows:
1. Pressing F1-CYCLE causes the grinding wheel to go to the program zero or home value if it is not already there.

2. From the program zero or home position, the grinding wheel is moved down to the rapid value at high speed.
