SOLIDWORKS CAM – Machining with Tombstone
We will be using the following model to perform assembly machining using a rotary option to machine parts on a tombstone feature.
In order for us to proceed, we need to make sure that we first define the following:
2. Tool Crib
3. Post Processor
5. Rotary Axis
We need to make sure that all these settings are configured properly or else, during the simulation of toolpaths, we may run into issues such as:
– Tool holder colliding with work piece
– Parts are incorrectly cut
– Errors in generating program
Once we are done with all of the setup, we can proceed onto the next step and define what objects we would like to machine.
To select parts to be machined, we will select the CAM Feature Tab and double click on Part Manager.
As we have 4 different side but using same part on each side, we can easily add the rest of the parts in by clicking the Add All Instances. This will automatically detect and insert all similar instances in the Manage Parts window. Once we are satisfied with the additions, we can click OK and proceed on with the next step.
The next step we have to do is to make sure that we define the stock for all the parts that are to be machined.
We will double click on Stock Manager, and ensure that your Stock Type is selected as Bounding Box.
Next we will scroll down to Create Stock and click Apply Current Stock Definition to All Parts
After we are done with the part and stock definition, we can begin to start generating our operations and simulations.
Click Extract Machinable Features.
Click Generate Operation Plan.
Before we proceed to generate the toolpaths and simulation, we will normally advise users to define the Tombstone feature so that it is easier to visually check how the operation will run.
If the fixture is not defined and the toolpath is generated and simulated, you will have a simulation that will would not include the Tombstone feature.
To define the Tombstone feature, we will double click Setup1 and select the Fixtures tab.
Next we will zoom out and make sure that the entire assembly is selected.
Once everything is selected, it will propagate the parts within the features list. We can click OK to close the window.
