This task shows how to optimize the order of operations in a program according to pre-defined sequencing rules. | ||
 |
The Sequencing rules have been set
up by the administrator. The Program settings under Tools > Options >
Machining are described in
Program settings. Make sure that the document in the sequencing rules path is accessible in Read/Write. A sample sequencing rules document is delivered with the
product at the following location: |
||
 |
1. | Create a program containing the
following operations.
|
|
| 2. |
Select
Rules Manager
to visualize the administrator's sequencing rule settings. Change these
settings as follows:
|
||
 |
 |
||
| 3. |
Select
Auto Sequence
to display the Auto Sequence dialog box. Click the Select All
button to select all the operations of the program.
Click Apply to sequence the operations according to the defined rules and priorities. |
||
| 4. | The program is re-sequenced as follows.
|
||
 |
You can click Undo if you want to cancel the auto-sequence results. | ||
| It is possible to impose a
constraint (called strong precedence) to force a group operations to
remain together after sequencing. Applying a strong precedence constraint means that in addition to imposing an order between two operations A and B, it is not possible to have another operation C between them. The sequence A - C - B is not allowed, only A - B is allowed if a strong precedence exists between A and B. For this, a parameter named For example, in auto-sequencing this could be used to prevent inserting a threading operation between a drilling operation and a reaming operation. Machining axis changes are taken into account in auto-sequencing without having to impose strong precedence criteria. |
