how to make a 3d cnc cam setup

by:QY Precision      2019-10-02
This instructable will guide you through the process of shooting any 3D surface made in Fusion 360 and make a 3D milling cam device to prepare for the CNC machine.
In the CAM workspace, we will build inventory (
Material to be carved out)
Size, selection tool (
In this case, a vertical mill)
, Enter the correct settings for the cut and create the toolpath that can run on other mills.
The model used in this structure is made using the process I described in this structure: this is a powerful 3D modeling platform that is easy to learn, but has endless potential.
With it, you can design complex 3D objects for almost any type of manufacturing, digital or otherwise.

First, switch to CAM workspace in the workspace drop-down-
The lower list in the upper left corner of the interface.
Next, click Settings> new settings \".
A generic stock will be automatically created and represented as a translucent box around the entity object.
The axis will be based on the model environment where Y is the \"up\" axis, but for CAM, Z must be the \"up\" axis.
To change the axis, just click the arm of the z-axis arrow and click any line in the Model Y-axis.
You can click on the arm of the z axis and click up-
Axis on model origin (
Note: The model origin must be opened in the model workspace).
The Cam origin should now be set to Z up, X points to the right from this angle, and Y points to the left along the bottom of the model.
If the X or Y axis does not point in the right direction, you can flip them by clicking on the end of the arrow.
To set the origin, you can click the origin and select the model origin, or you can click the origin (
White balls where X, Y and Z meet)
Part of the camshafts, if your part is placed on the model, click again on any point on the model or on the model origin.
The inventory tab will display the default offset in each dimension.
Since I don\'t want to leave any stock, I set all of these offsets to 0.
With our CAM setup done, it\'s time to create the milling operation.
There are a lot of options, but for carved surfaces like this, the best results will come from 3D pocket cleaning.
Enter 3D> pocket cleanup in the Ribbon menu.
The machining operations menu is to enter the position of all settings in order to create the correct toolpath for milling.
The first item in the list is the cutting tool.
Click the select button and select one from the list.
The default list included in Fusion is a good start, but when you go deep into CNC, you can always add more tool settings and save your own.
I chose a 1/8 ball nose 2-
Flute screw end mill, but you can cut similar surfaces with a lot of other types of drill bits.
The ball nose drill bit produces a smoother surface and is usually used for finishing after rough cutting with a flat head Mill.
For such a small project, I don\'t think it is necessary to create a rough cut first.
When you run a CNC mill, it is important to have the right settings.
The basic settings can be summarized with \"feed and speed.
You will see many variables in the Tools tab of the toolpath window, but I want you to keep a close eye on these two variables when you start using CNC: all other variables (
Cutting feed speed, feed per tooth, etc. )
When you adjust these two, it will be updated automatically.
The goal here is to optimize the feed and speed to cut the work as soon as possible without damaging the vertical mill.
If the feed speed is fast and the spindle speed is too slow, the vertical mill will break under the side pressure: If the feed speed is slow, the spindle speed is faster than the required speed, and the risk of breaking the vertical mill is very small, but the job takes longer than it takes: what you want is the blonde area: the spindle is fast enough to cut easily, the feed is as fast as possible, there is no risk of too much lateral strain: of course, the hardness of the material plays an important role in the appropriate feed rate.
For example, in order to avoid overheating, the metal needs a slower spindle speed.
The rigid foam is very soft and you can almost lift the feeding speed to a full tilt without worrying about breaking the vertical mill.
There will be soft wood somewhere between these two extremes.
General advice can be found in many places.
The CNC manufacturer provides advice like the manufacturer of the vertical mill.
If you want to dig deeper, there is no shortage of feed/speed calculators there, which will help you really dial in the perfect settings.
However, it seems to me that if you are doing production work, you just need to calculate all the settings perfectly.
I found the default settings for other factories to be a good starting point.
These are their suggestions for redwood, which are harder in scale than poplar trees, so it is safe to think that these settings are a good start.
Tool: 1/8 \"this is the final feed and speed setting for this milling operation, as suggested above.
Next, go to the geometry tab and click the surface you want to Mill.
The tool wants you to click on the edge of the boundary of the surface, as shown in the figure.
No need to touch other settings in this tab now.
Next, click the height tab to set the vertical dimensions of the milling operation.
Here\'s a quick overview of what to do here: the channels tab is where to set the cut channel.
The first important setting here is tolerance and you should set it to tolerance. 001.
With such a small machine and a small cut, there is no need to make this setting higher.
The second setting is the maximum rough machining step: this will set the distance the cutter moves in the Z direction when cutting.
Stepover distance is the lateral distance of the cutting tool when engraving a complex surface or surface plane.
When engraving with ball head grinding, it is important to choose a stepover with few residual materials (
The so-called fan)
Not spending as much time as possible.
I use 1/8 \"using Othermill \"(3mm)
Ball end grinding removes 9 squares with different stepover, increasing from 1/2 of the tool diameter to 1/10 of the tool diameter.
As shown in the following figure, 1/8 Ø produces the best results in the least amount of time.
At 1/7, scallops begin to be visible, but at 1/9 and 1/10, there is little difference between scallops and 1/8 pockets.
CNC is about optimization of time and quality.
This test saves you a lot of time when you use this tool more.
The F3D Fusion 360 Archive in this step can be used to run the same test on any machine.
Smaller steps can make the surfaces smoother, but the toolpath will always need to be cut if they are too small.
Here are the settings to note: Finally, click the link taband to set the gradient type to Profile.
Hover over this menu to display a preview of the type of operation-
The Profile looks like a smooth transition, but some others may also work.
Now click OK to see your toolpath.
Fusion will provide you with an animated preview of the toolpath before you send anything to the CNC machine.
This is great because it can help you catch errors before cutting anything.
Go to Action> simulation and you will get the timeline and control window at the bottom of the screen.
If the toolpath is turned off and inventory is turned on, you can see a preview of the milling operation.
Errors and possible collisions will be displayed in red in the timeline at the bottom, so you can make changes to the machining operations as needed.
After setting up the toolpath, it is time to create the gCode file (
A set of instructions that can be read by other factories).
Go to Operations> post-processing and select other factories \". cps -
General purpose \"other factory\" of the post processor \".
This saves the gCode file in a local folder that other factory control software can access.
