Feedrate and Spindle Speed Parameters

This tab contains controls for:

Feedrates

Transition
You can locally set the feedrate for a transition path to a Machining Operation B from a Machining Operation A or from a tool change activity. This is done by selecting the Transition check box in the Machining Operation dialog box for operation B.

For more information, please refer to the Setting a Transition Feedrate.

Replace RAPID by Air cutting feedrate
Select this check box to replace RAPID feedrate in tool trajectories (except in macros) by Air cutting feedrate.

The changes in unit of Air cutting feed-rate, are also reflected in the APT file output. Calculated cycle time in the Properties dialog box of Machining Operation also gets changed.

Note:

The feedrates and Air cutting feedrate is defined in linear (feed per minute) or angular (feed per revolution) units.

  • Angular: feedrate in revolutions per minute and unit is set to mm_turn.
  • Linear: feedrate in feed per minute and unit is set to mm_mn.

Spindle output
This check box manage output of the SPINDL instruction in the generated NC data file. The instruction is generated, if the check box is selected. Otherwise, it is not generated

Note:

The spindle speed is defined in linear (length per minute) or angular (length per revolution) units.

  • Angular: length in revolutions per minute and unit is set to mm_turn.
  • Linear: length in feed per minute and unit is set to mm_mn.

Dwell mode
Dwell setting indicates whether the tool dwell at the end of each path is to be set in seconds or a number of spindle revolutions.

Decimal values is used for the number of revolutions. For example, when machining big parts that have a large volume, it is useful to specify a dwell using a value of less than one revolution (0.25, for example).

Quality
The feed and speed values are computed according to the Quality setting on the Machining Operation.
Compute
Feeds and speeds of the operation is updated according to tooling feeds and speeds by clicking the Compute button.

Feeds and speeds of the Machining Operation is updated automatically according to tooling data and the rough or finish quality of the Machining Operation. See About Feeds and Speeds.
