Gripper Sizing — Soft/Fin-Ray Gripper (Food & Delicate)
Holding-force and sizing math for a soft/fin-ray gripper (food & delicate) including acceleration and safety factor.
Food gripping inverts the problem: force is capped by what the product survives, so you grow AREA, not pressure. Fin-ray and bellows fingers wrap to enlarge contact; the verdict flips to red exactly when no amount of squeezing can be both gentle and secure.
Formula
Note: Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.

About Gripper Sizing — Soft/Fin-Ray Gripper (Food & Delicate)
Gripper Sizing — Soft/Fin-Ray Gripper (Food & Delicate) computes the governing relationship F_available = p_max·A·n vs F_needed = m(g+a)·SF/µ_soft live as you type. Food gripping inverts the problem: force is capped by what the product survives, so you grow AREA, not pressure. Fin-ray and bellows fingers wrap to enlarge contact; the verdict flips to red exactly when no amount of squeezing can be both gentle and secure. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Gripper Sizing — Soft/Fin-Ray Gripper (Food & Delicate)
- 1Enter your values — Product mass, Peak acceleration, Max contact pressure, Contact area per finger and more (sensible defaults are pre-filled).
- 2Read the live results: Available normal force, Needed (µ=0.8 soft contact).
- 3Check the "with your numbers" line to see F_available = p_max·A·n vs F_needed = m(g+a)·SF/µ_soft substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Gripper Sizing — Soft/Fin-Ray Gripper (Food & Delicate)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula F_available = p_max·A·n vs F_needed = m(g+a)·SF/µ_soft with authoritative sources cited on the page (Schmalz — Vacuum handling calculation basics; Monkman et al., Robot Grippers (Wiley-VCH))
- ✓Food gripping inverts the problem: force is capped by what the product survives, so you grow AREA, not pressure.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the gripper sizing — soft/fin-ray gripper (food & delicate) use?+
It evaluates F_available = p_max·A·n vs F_needed = m(g+a)·SF/µ_soft, exactly as published. Sources: Schmalz — Vacuum handling calculation basics; Monkman et al., Robot Grippers (Wiley-VCH). The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Food gripping inverts the problem: force is capped by what the product survives, so you grow AREA, not pressure. Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.
When is this calculator the right tool for the job?+
Holding-force and sizing math for a soft/fin-ray gripper (food & delicate) including acceleration and safety factor. A free industrial robot kinematics & cell design tool. Fin-ray and bellows fingers wrap to enlarge contact; the verdict flips to red exactly when no amount of squeezing can be both gentle and secure. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
