Use this engineering calculation for a transparent preliminary estimate or independent arithmetic check when geometry, materials, loads, operating conditions, and units are defined consistently.

Lift Millimeters (mm)

Required number input.

Position Degrees (°)

Required number input.

Rise Degrees (°)

Required number input.

Simple-harmonic cam follower displacement over a specified rise angle, with zero at start and full lift at end. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Displacement Millimeters (mm)

The resulting displacement millimeters returned as a number.

• Simple cam motion defines displacement but not automatically acceptable velocity, acceleration, jerk, pressure angle, contact stress, undercutting, spring force, or dynamic response. Manufacturing geometry and follower type affect the realized motion.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check assumptions against drawings, measurements, current material data, and the applicable design code. Apply required load combinations and safety factors, then obtain qualified review and testing for consequential designs.

• Beam Reaction Uniform

  Each end reaction of a simply supported beam carrying a uniformly distributed full-span load.

• Bending Allowance Sheet Metal

  Sheet-metal bend allowance from bend angle, inside radius, thickness and specified K-factor: BA=θ(R+Kt).

• Draft Angle Height

  Lateral draft clearance h tanθ accumulated over mold or casting wall height.
