CNC Machine Tending Automation
Plan the robot, machine access, feeding, finished-part return, buffering and inspection as one machine tending cell—not as an isolated robot arm.
In one reference cell configuration, one feeding system serves two CNC machines, removes finished parts and stacks them. Final equipment and interfaces still require project review.
Machine tending is the complete flow around the CNC
A robotic machine tending cell moves workpieces into and out of a machine tool. A workable design also has to define where blanks wait, how parts are located, where finished parts return, and how the equipment exchanges status safely.
Part presentation
Define tray, conveyor or other line-side feeding before selecting the handling sequence.
Machine exchange
Review doors, fixtures, workholding, access and signal interfaces for the actual CNC.
Finished-part flow
Return parts to a defined position for stacking, buffering, inspection or the next operation.
One reference cell serves two CNC machines
In one reference configuration, one feeding system supplies two CNC machines, removes the finished parts and stacks them. Extension interfaces may connect the line with an AGV, AMR, belt conveyor or organizing device when the project requires it.

Separate blank presentation from finished-part placement
One tray-type concept includes finished-part stacking. A separate auxiliary-material feeding example shows a rotating store pre-loaded by an operator, robot-assisted feeding and secondary positioning before automatic pick-and-place.

A three-step route from the store to the machine
This sequence summarizes one auxiliary-material feeding example. It is a design reference, not a universal promise for every workpiece or machine.
Load the rotating store
An operator pre-loads the rotating storage positions before automatic handling begins.
Present the workpiece
In that example, a rotating table, robot arm and suction cups move the part toward the handling position.
Secondary positioning
The part is positioned again before the robot performs automatic pick-and-place.

Tending, buffer and inspection can be planned together
In one reference line configuration, robotic tending was combined with inspection machines and buffer loading/unloading equipment. The correct scope depends on what the next operation needs to know or receive.
Move blanks and finished parts through the machine exchange.
Decouple upstream presentation from downstream transfer where the project needs intermediate storage.
Reference examples include checks for dimensions, auxiliary material presence and character comparison; the required checks are defined for the actual part.
Use the stated thresholds as review gates, not guarantees
EVST uses two fit references as review gates. Both keep their qualifiers and must be checked against the actual machine, part and cycle definition.
CT below 60 seconds
One tray-type concept is intended for CNC machining applications with CT below 60 seconds. Confirm whether CT means machining cycle or handling cycle during application review.
Small VMC models at 850 or below
One reference configuration covers small vertical machining centers at model 850 or below; other machine models can be designed according to actual conditions.
No universal CNC interface claim
CNC communication and safety-interface details are defined per project. Compatibility must be checked machine by machine.
Check the part, machine and flow together
Send the CNC model, workpiece details and target flow for an application review.
Start with the part entering the CNC process
This page covers parts presented for CNC machining, including parts whose upstream origin may be stamping, injection molding or die casting.
Select the arm only after the cell requirements are clear
Payload, reach and repeatability belong to the robot-selection layer. Door access, part presentation, gripper design, buffering, inspection and safety belong to the complete cell.

The planning guide remains the dedicated information resource for that topic.
CNC machine tending questions
What is a CNC machine tending cell?
It is an automation cell that presents workpieces, loads and unloads a CNC machine, and returns finished parts to a defined position. Buffering, inspection, safeguarding and downstream transfer are defined per project.
Can one machine tending cell serve two CNC machines?
In one reference configuration, one feeding system supplies two CNC machines and removes and stacks finished parts. Robot quantity is defined per project, and feasibility depends on machine access, part flow and cycle review. Read the multi-machine planning guide →
Does the cell work with any CNC machine?
No universal compatibility is claimed. Machine doors, fixtures, workholding, access, control signals and safety interfaces must be checked for the actual CNC model.
What does the “CT below 60 seconds” note mean?
It is a suitability note for one tray-type concept. CT is not distinguished as machining cycle or handling cycle, so the definition must be confirmed during application review.
How are blank and finished parts separated?
One tray-type setup uses defined positions for presented blanks and finished-part placement. The actual tray layout and part limits are selected for the workpiece.
What information is needed for a machine tending review?
Provide the CNC model and layout, part drawings and weight, blank and finished-part presentation, workholding, machine-access sequence, target cycle definition, inspection needs, available floor space and required interfaces.
Define the part flow before selecting the machine tending cell
Send the CNC model and layout, part drawing and weight, blank and finished-part presentation, workholding, machine-access sequence, cycle definition, inspection needs and available floor space. EVST can review the cell concept and identify the information still required for selection.
