Notes: * Maximum values shown. Decreasing actual values will minimize wear during
coupling/uncoupling.
† Actual allowable values may be higher in some cases but higher offsets will increase
wear during coupling.

Tool Locating Features

The tool must be positively and repeatably located in the tool stand. A variety of
methods may be used to accomplish this. Whatever method is chosen it is important
that the required compliance or "float" be built into the locating system. A common
method is to use tapered dowel pins in holes. As the Tool Plate is lifted during
locking, the taper lets the tool float into its locked position even with small deviations
in robot position.
Other tool locating feature methods include balls and detents, dowel pins in notched
V-grooves, etc. Please consult ATI for recommendations or assistance with locating
feature design for your particular tooling.
Straight cylindrical dowel pins should not be used as they provide too much surface
engagement. During coupling and uncoupling the tool can bind on these pins due to
misalignment of the Master and Tool Plates.
Robot programming and locational repeatability are vital in tool pick-up and drop-off.
