Calculating based on norm tables

The figures in the norm table are obtained by interpolation.

Example

Norm times are available for drilling holes. These times vary with the thickness of the sheet and the diameter of the hole (see the following table)

Hole diameter in mm12345
Sheet diameter in mm
10.5001.0001.5002.0002.500
100.8001.6002.4003.2004.000
251.2002.3003.4004.5005.600

 

To enter the run time or production rate for an operation, zoom to the Calculate Norm Time (tirou0230m000) session to calculate the relevant value. In this example, you specify the norm table, the thickness of the sheet, and the diameter of the hole. The last two values are, for example, 12 mm and 3.6 mm. LN then computes the appropriate norm time through interpolation.

Hole diameter in mm33,64
Sheet thickness in mm102.400...3.200
