2.1 Master Interface
The Master plate is typically attached to the robot arm. An interface plate can adapt the Master plate to a
specific robot arm. Alignment features (dowel holes and bosses) accurately position and bolt holes secure
the Master plate to the robot arm or an interface plate. Custom interface plates are available from ATI upon
request. (refer to the drawings for technical information on mounting features.)
CAUTION:
Do not use more than two alignment features when securing a Master plate
to an interface plate. Using more than two alignment features can cause damage to
equipment. Use either two dowel pins or a single dowel pin, along with a boss/recess
feature to align the Master plate with the interface plate.
CAUTION:
Do not use dowel pins that are too long or do not allow the interface plate
and Master body to mate flush. Using dowel pins that are too long will cause a gap
between the interface plate and Master body and damage the equipment. Use dowel
pins that will not extend further than allowed by the Master body.

Incorrect Mounting of Master Plate
If the customer chooses to design and build an interface plate, consider the following points:
•
The interface plate should include bolt holes for mounting and either two dowel pins or a dowel pin
and a boss for accurate positioning on the robot and Master plate. The dowel and boss features prevent
unwanted rotation. Refer to the robot manual for robot mounting features.
•
The thickness of the interface plate must be sufficient to provide the necessary thread engagement for
the mounting bolts.
•
Dowel pins must not extend out from the surface of the interface plate farther than the depth of the
dowel holes in the Master plate.
•
If a boss is used on the Master plate, a recess of proper depth and diameter must be machined into the
interface plate to correspond with the boss on the Master plate.
•
Mounting bolts that are too long can create a gap between the interface plate and the Master plate,
which can damage equipment.
•
The interface plate must provide rigid mounting to the Master plate.
•
The interface plate design must account for clearances required for Tool Changer module attachments
and accessories.
