Tools
Tool call
With the T NC function, you call a tool in the NC program.
T corresponds to the TOOL CALL Klartext syntax.
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.
N110 T1 G17 S( VC = 200 ) | ; Tool call with constant cutting speed |
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.
Tool definition
With the G99 NC function, you can define the dimensions/allowance of a tool.
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!
110 G99 T3 L+10 R+5 | ; Define tool |
G99 corresponds to the TOOL DEF Klartext syntax.
Tool pre-selection
When you use the G51 NC function, the control prepares a tool in the magazine, thus reducing the tool-change time.
Refer to your machine manual.
A tool pre-selection defined with G99 is a machine-dependent function.
110 G51 T3 | ; Tool pre-selection |
G51 corresponds to the TOOL DEF Klartext syntax.
