This is a step-by-step tutorial on generating a toolpath with Blender CAM. For detailed description of panel options go [here](Blendercam-Panel-Descriptions).
|
||||
|
||||
|
||||
|
||||
## Change render engine
|
||||
First of all, change render engine to CAM to use the blender cam tool.
|
||||
|
||||
![Renderer selection](images/cam_render.png)
|
||||
|
||||
|
||||
## Change units in Blender
|
||||
|
||||
Change units to metric or imperial in Scene properties.
|
||||
![Renderer selection](images/milim.png):
|
||||
|
||||
|
||||
## Setup machine parameters
|
||||
|
||||
Setup machine parameters (postprocessor, maximum feed rate, work area, etc.) in 'CAM Machine' options.
|
||||
|
||||
![Machine setup](images/setup_machine.png)
|
||||
|
||||
## Add a new operation
|
||||
|
||||
Add new operation in the render properties.
|
||||
![New operation](images/newop.png)
|
||||
|
||||
Choose Parallel (or Outline Fill, Circles, Spiral, Block, Cross) in the Strategy dialog. Waterline option works best when [OpenCAMLib](Using-BlenderCAM-with-OpenCAMLib) is installed and other operations require curve data source. See how to generate curves from mesh model [here](Machining-technical-parts-using-Profile-and-Pocket-operations).
|
||||
|
||||
![Select operation](images/selectOperation.png)
|
||||
|
||||
In Object dialog select object being source of geometry for toolpath generation.
|
||||
|
||||
## Configure Cam Material and position object
|
||||
|
||||
In CAM Material size and position, set radius around model option to reflect the amount of stock material to be machined.
|
||||
|
||||
![Before position](images/beforePosition.png)
|
||||
|
||||
Manually position object inside work area, or use "Position object" option to position it automatically.
|
||||
|
||||
![Click position](images/positionObject.png)
|
||||
|
||||
![After position](images/afterPosition.png)
|
||||
|
||||
If the box representing material doesn't update, uncheck "Estimate from model" option and then check it again.
|
||||
|
||||
## Configuration of the active Operation
|
||||
|
||||
Set "Distance between toolpaths" to desired value.
|
||||
|
||||
"Distance along toolpaths" option determines accuracy. Lower values result in more accurate toolpath, but make computation slower and increase amount of resulting G-code.
|
||||
|
||||
Select "Use exact mode" - it improves accuracy. If you have [OpenCAMLib](Using-BlenderCAM-with-OpenCAMLib) installed, also select "UseOpenCAMLib" - it impoves accuracy and speeds up the computing time. OpenCAMLib also enables high quality algorithm from calculating waterline toolpaths.
|
||||
|
||||
CAM Movement:
|
||||
|
||||
Enter layer depth (in Step Down dialog), operation depth, start depth and optionally end depth (if "Depth from object" is disabled).
|
||||
|
||||
CAM Feedrate:
|
||||
|
||||
Set feedrate and spindle rpm. "Plunge speed" and "Plunge angle" allows slowing down feedrate when the cutter is moving down on steep areas.
|
||||
|
||||
Cam Cutter:
|
||||
|
||||
Set cutter tool number (used in G-code), type, number of flutes and diameter.
|
||||
|
||||
## Multiples operations in a chain
|
||||
|
||||
To join multiple operations into a single G-code file, use CAM chains dialog.
|
||||
|
||||
![New chain](images/newChain.png)
|
||||
|
||||
## Calculate Path and Generate Gcode file
|
||||
|
||||
Click "Calculate Path" to generate toolpath. If "Auto export" option is selected, G-code file will also be created.
|
||||
|
||||
![Calculate path](images/calculatePath.png)
|
||||
|
||||
![Calculate path view](images/calculatePath2.png)
|
||||
|
||||
## Quick look of the final result
|
||||
|
||||
Next click "Simulate operation" to create model representing machined material.
