Tools

Tool call

With the T NC function, you call a tool in the NC program.

T corresponds to the TOOL CALL Klartext syntax.

Tool call by TOOL CALL

With G17, G18, and G19, you define the tool axis.

Cutting data

Spindle speed

The spindle speed S is defined as spindle revolutions per minute (rpm).

Alternatively, the constant cutting speed VC in meters per minute (m/min) can be defined.

Feed rate

The feed rate for linear axes is defined in millimeters per minute (mm/min).

In inch programs, the feed rate must be defined in 1/10 inch/min.

The feed rate for rotary axes is defined in degrees per minute (°/min).

The feed rate can be defined with an accuracy of three decimal places.

Feed rate F

Tool definition

With the G99 NC function, you can define the dimensions/allowance of a tool.

 
Machine

Refer to your machine manual.

A tool definition created with G99 is a machine-dependent function.

HEIDENHAIN recommends using tool management for the definition of tools instead of G99!

Tool pre-selection by TOOL DEF

Tool pre-selection

When you use the G51 NC function, the control prepares a tool in the magazine, thus reducing the tool-change time.

 
Machine

Refer to your machine manual.

A tool pre-selection defined with G99 is a machine-dependent function.
