VR CIM Room 3
 
OBJECTIVE

1. To run an automated cell consisting of a lathe, a milling machine (miller), two robots a vision system linked by a conveyor..

2. To generate parts, process and routing schedules for the cell.

3. To dispatch schedules to the cell and create virtual chess pieces.
 

INSTRUCTIONS

Follow the step by step instructions whilst carrying out the described actions on your computer. The Instructions will take you through the different programs that make up the Virtual Reality CIM suite, which represent the stages that are necessary for automated manufacturing.

These are :        Process Planning
                            Shop Floor Layout Design
                            Route Planning
                            Scheduling
                            Dispatching
                            Manufacturing

N.B. Robot programming is handled in the Virtual Reality Robot suite.

6. As each machine is inserted you will see the following dialogue box:

 
 

7. Select the correct name from the drop down box and repeat for each component when requested.

 

8.   Make sure that the robot work envelope is able to reach all machines. You can do this by clicking on Robot1 and then using  VIEW>Robot Reach. Repeat the process for Robot2.
 

9.  Select  VIEW>Cell Structure. Check each cell by selecting from the cell list.

 

5.  Select VIEW>Transport Network. This will allow you to ensure that the components are linked by the transport system and that the correct relationships between the components exist If there is a break in the transport network, ensure that all machines are close to the conveyor stations.
