Sintering Shrinkage Allowance at 72% material correction factor: a worked example
Suppose material correction factor falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate fired dimension change from green size, shrinkage per millimeter, material correction factor, and fixed machining allowance.
The inputs for this scenario
- Green body dimension: 48 mm (held at the documented default)
- Linear shrinkage allowance: 0.18 mm/mm (held at the documented default)
- Material correction factor: 72 % (the input this scenario stresses; the baseline uses 100)
- Fixed grinding stock allowance: 0.25 mm (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Corrected shrinkage allowance = green dimension × linear shrinkage allowance × material correction factor.
- Total sintering allowance works out to 6.47 mm allowance at these inputs, and this is the headline figure for the scenario.
- Linear shrinkage allowance works out to 0.13 mm/mm at these inputs.
- Corrected shrinkage allowance works out to 6.22 mm allowance at these inputs.
- Fixed grinding stock allowance works out to 0.25 mm at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where material correction factor sits at 100% and the headline result is 8.89 mm allowance, this scenario comes in 27.21% below the baseline at 6.47 mm allowance.
- It computes the corrected linear shrinkage for a green dimension and adds a fixed grinding stock margin to give the total sintering allowance in mm. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
