Method 17 to 30 have the same operation as Method 1 to Method 14; however, these methods set the home position on the
dog but not on the Z-phase. The following figure shows the operation of the homing methods of Method 19 and Method 20.
Method 19 and Method 20 have the same operation as Method 3 and Method 4; however, these types set the home position
on the dog but not on the Z-phase. Also, Method 19 has the same operation as the dog type front end reference homing.
Method 20 has the same operation as the dog cradle type homing; however, the stop position is on the dog but not on the Z-
phase.
