• “Teach” Input Programming System ... 
   Operator simply moves the grinding wheel
   manually to the grinding start position
   and using an input key teaches that position 
   to the machine, then he moves the 
   wheel to the cross reversal position and 
   using the input key, teaches that position 
   to the machine, etc.
   He then inputs stock removal, air cut,
   dressing interval, etc.,  and the CNC control 
   automatically calculates total movement and
   all start and stop points.
 
• “Drawing” Input Programming System ... 
   Input the actual dimensions from the workpiece 
   drawing and the control automatically 
   calculates the cycle sequence.
 
• Built-In Conversational Dress Programming ... 
    is based on the three basic types of dressing 
    menus -- “Side”, “R”, “V”, and “SLOT”.
