The parameters of the "Multiple machining programmed by means of an arc chord (G65)" cycle have been programmed wrong. These may be the probable causes:

1. Some mandatory parameter is missing.2. The parameters of the cycle have not been edited in the correct order.
2. Some data might be superfluous.

This type of machining requires the programming of:

And one of the following data:

The rest of the parameters are optional. The parameters must be edited in the order indicated by the error message.

X/Y Distance from the center to the first hole.

B Total angular travel.

I Angular step between machining operations.

K Number of machining operations.

X/Y Distance from the center to the first hole.

A Angle of the matrix of the chord with the abscissa axis (in degrees).

I Length of the chord.
