Base PlateBeta

Base Plate Sizing Card

Estimate thickness with a simple stiffness model, round to standard thickness, and check machine-table compatibility.

Inputs

Plate span L [mm]

Plate width b [mm]

Equivalent load F [N]

Allowable deflection ? [mm]

Material (E and density)

Results

Calculated t (theoretical)22.14 mm

Recommended standard thickness25.00 mm

Estimated weight at calculated thickness23.46 kg

Estimated weight at recommended thickness26.49 kg

Estimated deflection at recommended thickness0.07 mm

Formula

? = F*L^3 / (4*E*b*t^3)

E = 210000 N/mm²

Machine Table Compatibility

T-slot spacing and orientation are definedBolt pattern fits machine table layoutLifting points/rings are definedDowel/location holes are dimensioned clearly

Notes Table

References

Model: ? = F*L^3 / (4*E*b*t^3), solved for t.
Use E in N/mm² (Steel 210000, Aluminum 70000).
Standard thickness selection improves sourcing and manufacturing consistency.
Validate final design with FEA and machine-table constraints.
