Friction-only holding screen

Fixture clamping force

Inputs

Declared horizontal machining forceFcutUser-entered horizontal machining force requiring frictional restraint.

Declared clamp/workpiece frictionμ—User-entered static friction coefficient for this narrow horizontal-force screen.

Declared force multiplierM—User-entered multiplier for the stated force context; it is not a prescribed safety factor.

Multiplier-adjusted horizontal force

3,600

Friction-only required normal force

18,947

Friction capacity at required normal force

3,600

Fdesign = Fcut M; Nrequired = Fdesign/μ; Ffriction = μN

Method

Calculate the normal clamping force required to resist a horizontal machining force through friction and force multiplier.

Fdesign = Fcut M; Nrequired = Fdesign/μ; Ffriction = μN

When

Don’t

This is a friction-only horizontal-force screen. It does not analyze stops, lift, moments, clamp geometry, load distribution, workpiece deformation, vibration, dynamic loads, machine table stiffness, clamp capacity, fixture selection, or safety approval.
