Endcut Radius Definition

The endcut standard contains endcut types with zero, one or two radius definitions. The radii, denoted R1 and R2, are defined in the endcut table according to specification for each endcut type. For illustration purposes endcut type 11 is used below.

The radii definitions R1 and R2 may encode the following endcut geometry:

• Scallop radius

• Fillet radius

• Snipe

• Asymmetrical snipe

• Other endcut type specific geometry

A scallop radius is defined by a positive number less than 1000.

In the illustration below, using endcut type 11, R1=35 and R2=50.

A fillet radius is encoded as a positive number greater than 1000. The radius is received by subtracting 1000. In the illustration below R1=1050 and R2=1020.

A snipe is encoded as a negative number greater than -1000. The geometry is the same as for corner notch of type KS. The lengths of the notch axes are the absolute value of the encoded number. Below R1=-50 and R2=-50.

An asymmetrical snipe is encoded as a negative number less than -1000. The geometry is the same as for corner notch of type KSA. The axis C1 and C2 of the notch are encoded by first calculating C1*1000+C2 and then negating the result. Below is shown an end cut of type 11 with R1=-30050 and R2=-40020. When decoding R1 the same geometry as for corner notch KSA30*50 will be received. R2 corresponds to corner notch KSA40*20.

At last end cut type specific geometry may be encoded in the radius definition. As an example of this please see end cut Type 39 in Endcuts for T-bars. There, due to lack of dimension parameters, a distance is encoded into the R2 definition.
