Determine the target heating temperature to expand a bore for a slip-fit assembly.
Inputs / Parameters
Formulas used: Total Expansion Required = Interference + Clearance Temperature Delta (ΔT) = Total Expansion / (Diameter × CTE) Target Heater Temp = Ambient + ΔT Clearance ensures the shaft can drop in easily without hanging up during the
rapid cooling phase. Typical slip clearances range from 0.001" to 0.003".
