These are the menu items under the Operation | Graphic Display Window | Clearance Moves submenu:
The Auto Insert Moves menu option (Operation | Graphic Display Window | Clearance Moves | Auto Insert Moves) opens the Auto Insert Moves dialog box. You can use this dialog box to add clearance moves (MOVE/POINT commands) between all features or between selected features. For information on how to do this, see the "Using Auto Insert Moves" topic below.
Auto Insert Moves dialog box
When you click OK, PC-DMIS inserts the MOVE/POINT commands.
PC-DMIS does not place move commands prior to the first feature; make sure there is a clear path between the probe's start position and the first feature.
All features - PC-DMIS places the move commands between all features.
Selected features - PC-DMIS places the move commands between a range of two features that you can select from this area. The Starting feature and Ending feature lists beneath this option show the features. (You can also select the two features from the Edit window before you open this dialog box.)
Maximum Move Length - This value defines the maximum length of a move. This value is in mm or inches, based on the measurement routine's units. This means any MOVE/POINT commands that the algorithm calculates to move the probe from one location to another cannot exceed this value.
PC-DMIS attempts to go directly to the next feature, but compensates for collisions by inserting clearance move commands. It continues this process until it defines a collision free path to the next feature. More than one move command may be inserted between features. The higher the value, the lower the amount of time PC-DMIS spends calculating these moves. The recommended value is 100 mm (3.93 inches).
Collision Safety Distance - This value defines a safety distance around the part. A move is considered a safe move if it moves the probe this distance away from the part. To prevent the creation of too many moves, the value of Maximum Move Length should be greater than the collision safety distance value.
Delete existing moves - This determines whether to delete any pre-existing move commands in the measurement routine.
For dual-arm measurement routines, PC-DMIS inserts MOVE/EXCLUSIVE_ZONE commands as needed to guard against the two arms colliding during execution.
Minimum Solution time (sec) - This value is the minimum number of seconds that the algorithm uses to plan a move between two feature commands. A higher value increases the accuracy of the move, but it also increases the computation time. The recommended value is 1 second.
Maximum solution time (sec) - This value is the maximum number of seconds that the algorithm uses to plan a move between two feature commands. A higher value increases the accuracy of the move, but it also increases the computation time. The recommended value is 3 seconds.
Bounding box offset - This area lets you define a cubic region or cubic-like rectangular region that PC-DMIS uses to calculate the automatic insert moves. This region is not a clearance cube. You may find this functionality useful if you have a fixture or some other obstruction around certain regions of your part and you don't want PC-DMIS to calculate moves near those areas. In that case, you can define a region, and PC-DMIS calculates the moves only within this region.
The maximum and minimum ranges for each axis let you define a more precise space for PC-DMIS to calculate the moves.
The offset values are based from on the surface sides, not from the alignment origin. This value is in mm or inches, based on the measurement routine's units.
The software adds this value to the CAD model's existing bounding box offsets. The recommended value is 1000 mm (39.3 inches).
The small up and down arrows in each box adjust the value by 10 percent of the maximum size of the bounding box with each click.
Visibility - This switch lets you show or hide the bounding box region in the Graphic Display window while the dialog box remains open.
Example 1 - This
shows the bounding box at 100 mm in all axes:
Example 2 - This shows the bounding box
with minimum x, y, and z values of -80, 20, and -45 and maximum
x, y, and z values of 4.0, -20, and 40:
This menu item (Operation | Graphic Display Window | Clearance Moves | Within Feature) only works in QuickFeatures mode. If the menu item is selected with a check box and you create a QuickFeature, PC-DMIS checks the probe path inside the feature and adds clearance moves as needed within the feature. This is different from the With Feature Creation menu item below, which adds clearance moves between features.
You can choose With Feature Creation menu item (Operation | Graphic Display Window | Clearance Moves | With Feature Creation) to enable it or disable it. The menu item shows checkmark when enabled.
With this menu item enabled, PC-DMIS uses a simple algorithm to automatically insert MOVE/POINT commands as you add features to the measurement routine. The angle between the features must be within a range of 30 to 150 degrees. The algorithm cannot solve anything outside this range. For example, two circle features at different depths but on the same face, results in a 0 degree angle between them and can't be solved. When inserting the move commands, this menu item behaves similarly to the Auto Insert Moves dialog box and uses one feature above and below the newly inserted feature as the start and end features. This menu item also uses the distance defined in the CollisionMoveClearanceInMM registry entry.
The QuickFeatures menu item activates a new algorithm to generate safe clearance moves as you add QuickFeatures. Automatic safe moves between features that use different probe tip angles are not yet supported. You must manually define those moves.
This functions only in Offline mode.
The With Collision Detection menu item is not supported for QuickFeatures.
The With Feature Creation menu item (Operation | Graphic Display Window | Clearance Moves | With Feature Creation) must be selected for this to become enabled. The menu item shows checkmark when enabled.
If you enable the With Collision Detection menu item, the software extends the functionality of With Feature Creation so that you aren't limited by the angle restrictions between features. PC-DMIS uses the collision detection algorithm to detect collisions instead of the simple algorithm. It provides clearance moves between the range of features. For each collision found, it then inserts the appropriate clearance moves.
