| Calculate Norm Time (tirou0230m000) |  |
| Use this session to calculate the cycle time or production rate of an operation in the Routing Operations (tirou1102m000) session. ERP LN calculates the values by means of a norm table. ERP LN determines all possible norm times for operations by interpolation between the minimum and maximum values for the two axes. You can also specify a factor to calculate the norm time, for example, the number of holes to be drilled.

Fields | Description
Norm Table | A table that contains the times required to perform a task (norm times), or the numbers of times that a task can be performed in a specific unit of time (norm units). The norm times or norm units depend on two series of values presented in the columns (X-axis) and the rows (Y-axis) of the table. Example The time that it costs to drill a hole depends on the material's thickness, and the hole's diameter. A norm table that contains norm times can look like this:
| Thickness (mm)
Diameter (mm) | 1 | 2 | 3 | 4
0.5 | 1.2 | 1.4 | 1.6 | 1.8
1.0 | 2.2 | 2.5 | 2.8 | 3.1
1.5 | 3.1 | 3.5 | 3.9 | 4.3
The norm time to drill a hole with diameter 1.0 in a material with thickness 2 is 2.5.
Norm Time Table Type | Allowed values:
X-Axis Description | The actual physical quantity on the x-axis.
Y-Axis Description | The actual physcial quantity on the y-axis.
Factor for Norm Time | A factor to calculate the norm time, for example, the number of holes to be drilled.
Calculated Norm Time | The time that is required to perform a task. That time is determined on the basis of two values in the norm table. Example To drill a hole with a diameter of 5 mm (first value) in a sheet with a thickness of 8 mm (second value) takes 0.5 minute (norm time).
Calculated Production Rate | The number of times that a task can be carried out for a specific unit of time (minute or hour). That number of times is determined on the basis of two values in the norm table. Example Each minute, 5 boards with a thickness of 5 mm (first value) and a width of 60 mm (second value) can be sawn. Consequently, the norm unit is 5.
