Custom machine tending cells: layout and integration checklist

A custom machine-tending cell is often necessary when the machine doorway, workholding, part family, or surrounding floor space does not suit a standard package. Custom engineering should solve those constraints explicitly. Start with a measured layout and complete machine cycle, then ask each supplier to show how its design handles the difficult positions and operating exceptions.

Capture more than the floor plan

Measure the machine opening, spindle or fixture location, door travel, control-panel position, and obstructions around the loading path. Include overhead and below-table features. Record the path taken by the part and tool, rather than drawing only the robot base and a circle representing nominal reach.

Request a reach study using the proposed tool, part, base height, and approach directions. Check the deepest insertion, extraction of the largest finished part, and clearance when a second gripper is occupied. Review maintenance access with the machine owner: filters, chip conveyors, service doors, and lubrication points may be accessible today because no robot stands in front of them.

Our payload and reach checklist helps assemble the necessary inputs. Nominal reach is a starting filter; the cell needs a feasible sequence in the actual geometry.

Assign every machine interface

List the handshakes between machine, robot, workholding, and any external controller. Include machine ready, door state, spindle or process state, clamp status, part present, cycle complete, and alarm. Determine which interfaces the machine manufacturer supports and who is authorized to modify the machine. A button-pressing demonstration does not define the full integration boundary.

OSHA's robot guidance treats the complete application in its risk assessment. Have qualified personnel establish the required safeguarding and safety-related interfaces. Ordinary process signals and safety functions need clearly assigned roles.

Design for the condition of real parts

Inspect blanks and finished pieces after representative production. Note temperature, coolant, chips, sharp features, and changing grip surfaces. Ask how the tool is protected from the operating environment and how hoses or cables are routed through the complete motion. Specify acceptable cosmetic marks and the consequence of gripping an out-of-tolerance blank.

Robotiq's machine-tending design lesson identifies chip and coolant removal from parts and workholding as a repeatability issue. In your scope, assign cleaning equipment, waste control, inspection, and maintenance effort rather than leaving them as an operator's unofficial task. Have the integrator validate the chosen cleaning process for the machine and hazards involved.

OnRobot lists machine-tending gripper options for different part geometries. Require sample trials with the actual raw and finished surfaces. If changing fingers or tools is necessary, include the storage, identification, and setup process in both the floor plan and changeover estimate.

Place replenishment and recovery first

Draw where an operator stands to replenish blanks, remove finished work, inspect a part, and respond to each common stop. Avoid a design whose normal running layout is compact but whose recovery requires moving unrelated equipment. Include empty trays, rejected parts, and gauges in the space allocation.

Use the tray loading and unloading guide to specify inventory capacity and docking. Establish whether a partially processed part can remain in the machine during a tray exchange or restart. The correct answer depends on your machining process and control design, so it should appear in the integrator's sequence documentation.

Turn custom work into reviewable deliverables

• Measured cell layout and verified motion study for the agreed part family.
• Interface list with named owners and machine-manufacturer dependencies.
• Tooling and fixture drawings, replaceable wear parts, and spare recommendations.
• Application risk assessment, validation records, and operating procedures.
• Acceptance run covering changeovers, normal replenishment, and approved recovery tests.

Request a FAIRINO machine-tending layout

For a value-focused custom cell, compare a FAIRINO-based layout against the complete machine cycle and installed budget. Review the FAIRINO machine-tending planning inputs and model comparison before settling on an arm. The suitable configuration depends on doorway access, workholding, tool load, supported machine interfaces, and approved recovery. Request a FAIRINO machine-tending quote with a measured layout, machine make and model, part drawings, and full-cycle video. Ask the proposal to identify each machine modification and integration responsibility.
