How do I size gripper cycle capacity against a cell's target cycle time?

The Gripper Cycle Capacity calculator uses open and close time, stroke, and settling time to return picks per minute the gripper can sustain. Compare that against the cell's required cycle time. If it falls short, check whether stroke length, actuation pressure, or the vacuum settling captured in Vacuum Cup Loss is the limiter before you move to a faster or larger gripper.

How much compressed air will an EOAT draw, and can the system supply it?

The Pneumatic Air Usage calculator takes cylinder or vacuum generator size, actuations per cycle, and cycle rate to return air consumption in SCFM. Vacuum generators are especially thirsty, so pair it with Vacuum Cup Loss. If demand exceeds supply you get grip failures under load, and switching to electric grippers or adding a vacuum reservoir is often cheaper than upsizing the compressor.

How do I know if my tool plus part exceeds the robot's payload?

Use the Payload Derating calculator. It adds tool mass and part mass, then derates against the robot's rated payload based on the center of gravity offset and wrist orientation, since payload capacity drops sharply as the load moves away from the flange. Robot Compatibility Risk uses the same inputs to flag when a tool needs a larger robot or a lighter, closer-coupled design.

What spares and wear reserve should I carry for a gripper fleet?

Jaw Wear Reserve estimates replacement intervals for jaws, fingers, and vacuum cups from cycle count and abrasiveness, while Spare Part Buffer sizes the on-hand stock to avoid line-down waits. Combine both with Field Failure Reserve to cover unexpected failures. Vacuum cups and compliant fingers are consumables, so budgeting their replacement rate up front keeps a running cell from surprise stoppages.

How do I price custom EOAT including design and build labor?

Build the cost from EOAT Assembly Labor, Custom Bracket Machining Cost, Cable Routing Labor, Sensor Calibration Load, and Design Review Hours, then apply Tooling Amortization if the cost spreads across a production run. Quote Margin rolls these into a price. Design and cable routing labor are commonly underestimated on custom tools, so capturing them explicitly keeps a bid from eroding margin later.

How do I show a customer the payback on an EOAT investment?

The Application Payback calculator compares the tooling and integration cost against the labor or cycle-time savings the automated cell delivers, returning a payback period in months. It draws on Tooling Amortization and Gripper Cycle Capacity so throughput gains are realistic. A typical justified EOAT project targets payback under 18 to 24 months, and the calculator shows which assumptions most affect that figure.
