Formula of Angle Error
Absolute accuracy error
| Example | Measurement method | S | L、D、R | P |
|---|---|---|---|---|
|
1. Vertical measurement (L Jig Bracket) |
Leveling at 0 degree , rotating 90 degree
|
Arc seconds = | Length L(mm) = | Error(um) = (excluding the verticality error of the machine) |
|
2. Faceplate method (Rotary Index Plate Special Machine) |
Measurement point
|
Arc seconds = | Diameter D(mm) = | Error(um) = (excluding the verticality error of the machine) |
|
3. Radius method: (Grinding Machine C Axis) |
Leveling at 0 degree and measure 90 degree
|
Arc seconds = | Radius R(mm) = | Error(um) = (excluding the verticality error of the machine) |
