7.3 Height Procedures

The Height procedure is performed in order to determine the Cutting

Chuck position along the Z-Axis.

Height is performed by lowering the Spindle until the edge of the Blade

makes contact with either the Cutting Chuck (Contact Height) or the

Height Device (Button Height). The Height Device, located next to the

Cutting Chuck, can be either a Mechanical Button or an optical device

(Non-Contact Height Device).

Height procedure performed during the cutting process is referred to as

Process Height. Process Height is performed throughout the cutting

process in order to compensate for changes in the Z position of the cutting

edge due to the Blade wear. Process Height is usually a non-Chuck Height,

meaning it is performed on the Height Device.

However, the User can configure the System so that Process Height is a

Contact Height, meaning it is performed on the Cutting Chuck by changing

the Height Type parameter in the Recipe from Regular (process height

performed in the Height Device) to Defer (process height performed on the

Cutting Chuck). This option is generally used in case there is a problem

with the Height Device. It allows the user to keep using the machine, while

the problem is being solved.

The User determines when Process Height is performed by configuring the

following two parameters in the Height category of the Recipe:

• Height Check Units: Determines whether Process Height is

performed after a defined number of cuts or after a defined cut length.

• Height Check Rate: Determines the number of cuts or the total cut

length after which Process Height is performed.
