NC Servo Feeder Selection Worksheet

Selection Worksheet

Collect the Data Needed to Select an NC Servo Feeder

A useful model recommendation starts with material, pitch, production cycle, press interface and line-layout data. This worksheet makes those inputs explicit before a quotation is requested.

Use this page as an engineering intake form—not an automatic model selector. It helps prevent missing data, but final capacity and cycle suitability must be checked against the selected feeder, press, die, material and project drawings.

MaterialWidth, thickness, grade, strength and surface condition.

MotionFeed pitch, sequence, target SPM and changeover pattern.

InterfacePress model, timing source, release and safety boundaries.

LayoutPassline, direction, coil data, supports and available space.

NC servo feeder installed beside a stamping press for model selection — Model selection must use the actual press, strip, die and production-cycle data.

Automatic press feeding equipment and material path — Passline, material path, upstream equipment and interface scope are part of the selection record.

How to Use This NC Servo Feeder Selection Worksheet

1. Record ranges, not one nominal job

List minimum and maximum strip width, thickness and pitch. A model selected from one easy part may not cover the full production range.

2. Separate known values from estimates

Mark values taken from released drawings, press manuals and material certificates. Label assumptions so they can be confirmed before order release.

3. Attach evidence

Include press nameplate photos, die layout, material data, current line photos and the available signal list where possible.

4. Ask for a cycle and interface check

Do not accept a model based only on maximum width. Ask the supplier to validate capacity, timing, grip, release and the installed scope for the real job.

A. Material and Strip Data

Worksheet field	Record your requirement	Why it matters
Material type and grade	____________________________	Material behavior and required roll force differ by grade and temper.
Minimum / maximum width	________ / ________ mm	Defines the usable roll face and guiding range.
Minimum / maximum thickness	________ / ________ mm	Affects grip, frame load, opening range and upstream straightening.
Yield / tensile strength	________ / ________ MPa	Strength data is needed for a defensible capacity review.
Surface condition	Dry / oiled / coated / polished / other: ________	Changes traction, marking risk and roll-surface requirements.
Strip edge and coil set	Describe burr, camber, edge wave or coil set: ________	Poor incoming strip condition can look like a feeder accuracy problem.

B. Feed Sequence and Production Target

Worksheet field	Record your requirement	Why it matters
Minimum / maximum feed pitch	________ / ________ mm	Pitch determines travel required in each press cycle.
Feed sequence	Single pitch / multi-step / alternating / other: ________	Complex sequences favor programmable control and require timing review.
Target press speed	________ SPM at pitch ________ mm	Always pair SPM with pitch and the real material.
Required accuracy method	Part tolerance / strip index / pilot-controlled: ________	Feeder repeatability and finished-part tolerance are not the same specification.
Jobs and changeovers	________ jobs; ________ changes per shift/week	Recipe storage and setup method affect total operating value.
Batch and recipe needs	Batch count / recipe storage / upstream-downstream data: ________	Defines controller and operator-interface requirements.

C. Press, Die and Control Interface

Worksheet field	Record your requirement	Why it matters
Press brand, model and type	____________________________	Provides the mechanical and control basis for integration.
Press tonnage and stroke data	____________________________	Helps identify the actual machine and available timing documentation.
Timing source	Mechanical cam / electronic cam / encoder / PLC / unknown	The feeder must receive a defined, validated feed window.
Die pilots and release	None / required; release method and timing: ________	Release must occur only in the approved die and press sequence.
Feed-complete requirement	Required / not required / unknown	Defines whether the press waits for a positive feeder status.
Safety and fault interface	E-stop / guards / misfeed / alarm / reset: ________	Responsibility boundaries must be agreed in the project risk assessment.

D. Coil Line and Installation Data

Worksheet field	Record your requirement	Why it matters
Feed-line height	________ mm; datum: __________________	Mounting cannot be finalized without a common approved datum.
Feeding direction	Left to right / right to left	Affects feeder orientation, controls and upstream layout.
Available mounting space	W ______ × D ______ × H ______ mm	Confirms bracket, guarding and maintenance access.
Coil data	Weight ______ kg; ID ______; OD ______ mm	Used to coordinate decoiler, straightener, loop and supports.
Upstream equipment	Separate / compact / 2-in-1 / 3-in-1 / existing: ________	The feeder should index strip, not pull against uncontrolled coil tension.
Utilities and environment	Power ______; air ______; temperature / contamination: ________	Special utilities or environments must be specified before manufacture.

Selection limit: this worksheet does not calculate motor torque, roller traction, frame load, acceleration limits or a safe press timing window. Those checks require verified model data and project-specific engineering. Do not infer suitability from maximum strip width or catalogue feed speed alone.

Choose the Feeder Architecture Before the Exact Model

NC servo feeder: prioritize when pitches vary, recipes matter, jobs change frequently or electronic integration is required.
Mechanical roller feeder: consider for compatible presses running stable fixed-pitch repeat work.
Mechanical gripper feeder: consider for a validated short-pitch, high-cycle precision application with a compatible press.
Air feeder: consider when the application is straightforward and the required pitch, cycle and air supply can be proven.

Use the air vs roller vs servo vs gripper feeder comparison when the architecture is still undecided.

What HENLI Should Confirm From the Completed Worksheet

Review item	Expected output
Capacity fit	A named model or model range checked against width, thickness, strength and contact conditions.
Cycle feasibility	Confirmation against the stated pitch and target SPM, including the applicable feed and release sequence.
Press connection	Defined mounting, passline, direction, timing source, I/O and responsibility boundary.
Installed scope	A list of included feeder, bracket, controller, release, guarding, cables, options and excluded work.
Validation plan	Agreed sample material, test conditions, measurements, evidence and acceptance authority.

Files to Attach to a Selection Request

Press nameplate, model and relevant pages from the approved press manual.
Part and strip layout showing pitch, pilot holes, progression and material direction.
Material certificate or confirmed grade and strength range.
Photos or drawings of mounting space, passline and existing coil equipment.
Current electrical I/O list or control drawing when integration is required.
Representative strip or a defined sample-trial plan for sensitive surfaces or unusual material.

Frequently Asked Questions

Why does this page not automatically output a feeder model?

A defensible model choice depends on proprietary model limits, traction, acceleration, material behavior, press timing and installed interfaces. A simple public formula could give false confidence. The worksheet makes the inputs auditable; HENLI then checks them against current model data.

Is strip width and thickness enough for selection?

No. Include material strength, surface condition, pitch at target SPM, die release, press model, passline and upstream line behavior. A feeder can fit the dimensions and still fail the cycle or interface requirement.

Can I use estimated values at the quotation stage?

Yes, if estimates are clearly marked. The final order should identify which values must be confirmed and who owns that confirmation before design or manufacture is released.

What if the same feeder must run many different parts?

List the full operating envelope and identify the worst-case job for each factor. Maximum width, maximum thickness and highest SPM may belong to different parts and should not be incorrectly combined without review.

Selection path: Review the servo feeder types and working-principle guide before filling this worksheet, then use the price factors and total-cost guide to compare quotations on the same scope.
