In this lesson, we'll look at profile leads and transitions.
00:06
After completing this lesson, you'll be able to: Modify profile toolpath leads and transition settings and modify the Safe Z distance in the setup.
00:17
In Fusion 360, we're going to carry on with our turning CAM setup.
00:21
Now that we've taken a look at creating some basic profile roughing and finishing toolpaths,
00:26
we want to talk a bit more about some of the settings for profile leads and transitions.
00:31
To do this, we're going to focus on our profile finishing toolpath.
00:35
First, I'm going to go to a top view.
00:37
I'm going to rotate it so that the part is rotating and fixed on the left side as it would be in the machine.
00:44
Notice that the tool is coming from positive X.
00:47
And if we take a look, we can see different colored lines that are representing different segments of the toolpath.
00:54
The yellow motions are going to be rapid.
00:56
The green are going to be our leads or transitions and the blue lines are going to be our cutting.
01:02
So we want to take a look at the options inside of this toolpath by right clicking and editing and then going to our Linking parameters.
01:10
The first thing that I want to note is at the very top we have High Feedrate Mode.
01:15
The default is going to be preserving the rapid movements, but we can also always use high feed.
01:21
Some of these settings are going to depend specifically on your machine, but I'm going to default to preserving the rapid movements whenever possible.
01:30
The next thing that we have is the Approach and Retract.
01:33
The Approach and Retract are going to define how the tool should be positioned at the beginning and the end of the operation.
01:40
So by default, this is going to use the Safe Z which is defined in our setup.
01:47
So I'm going to select OK without making any changes.
01:50
I'm going to right click on our setup and take a look at our Safe Z distance.
01:55
Right now the Safe Z distance is in the front of the part plus 0.19685".
02:02
Remember that we have a small amount of stock 0.5 that we're removing,
02:07
but this is an additional almost 0.25" in front of the part that we don't necessarily need to go to.
02:14
A reason why you might go to that distance is if the spindle is stopping during a tool change,
02:20
and your machine needs a certain amount of time to spin up before the tool starts to enter.
02:26
In this case, I'm going to reduce this to 0.1, I'm going to say OK and I'm going to regenerate these toolpaths by going to Actions and Generate.
02:37
Now we can go back into our profile finishing and go to our Linking parameters and note that now our Approach and Retract are still using Safe Z.
02:47
However, we modified it for all of the operations based on our setup.
02:52
If we want to use a specific value, for example, if we know that we've removed a lot of material from the front of a part,
02:59
and we don't necessarily need it to retract as far, we can modify this based on a specific point,
03:07
and this will be based on those values using our leads and transitions.
03:13
The next thing that we want to do is we want to talk about those leads and transitions.
03:17
Right now the Lead-In Radius is 0, meaning that it's coming straight in.
03:22
If we want to have a Lead-In Radius before it comes into the cut, we can enter a value here.
03:28
I'm going to use a large value of 1" so that we can take a look at what this means as we're entering and exiting our cuts.
03:35
Now this is an exaggeration and this is a much larger value than you would ever use.
03:40
But you can see what's happening as it's affecting the leads and transitions for multiple cuts, not just the front edge.
03:48
You can see that it's using this large radius even as it's entering this groove.
03:53
So of course, we're going to reduce this value as it's much too large.
03:56
We're going to go back and we're going to set this back to 0 as we can come in straight to the cuts.
04:02
Because everything on this part is nice and prismatic, we don't have any big curves that we need to worry about.
04:08
The next thing that we want to talk about is this Linear Lead-In Length.
04:11
Again, we're going to exaggerate this by making it much larger than it needs to be at 1", and we're going to say OK.
04:19
So now you can see these green moves are coming in a full inch before it gets into the cut.
04:25
Once again, these are much too long and notice that it's coming into all of the different cuts and leading out of all of the cuts.
04:32
So at the very end, what's happening is this is likely going to intersect with our chuck because this is where it's holding our part.
04:39
So we do have to be extremely mindful when we start manipulating these values.
04:43
In reality, I'm going to have a much smaller value, such as an eighth of an inch and I'm going to use that 45 degrees.
04:50
And for example, if we wanted to modify the Lead-Out value, we can determine it specifically based on our criteria.
04:58
If we have a chuck in the way or not a lot of room on the back of the part,
05:02
then we might want to use a smaller value for the Lead-Out than we have for the Lead-In.
05:07
For example, instead of 45 degrees, maybe I want to do 80 degrees on the Lead-Out.
05:12
So this means that as its leading out, it's coming back and away from the chuck rather than going up and toward it.
05:20
So again, these values can be modified specifically based on Lead-In or Lead-Out,
05:25
but you do need to be aware that they don't only affect the start and the end,
05:29
but they will also affect things like where we're entering and exiting the cut for something like this groove.
05:35
Now that we've made those adjustments, let's make sure that we do save this,
05:39
before we move on and take a look at other types of geometry and toolpaths that are helpful when we're using CNC lathes.
