 ### Climb vs conventional milling 
 You can see a big difference in the edges with conventional and climb. Climb milling leaves a lot more dust and splinters on the edges. But as Neil explained climb is better when you're finishing a hole through. That will leave a clean hole. For surface cutting is conventional better.

 ## Assignment
 ### Inspiration
 
 For this assignment I used some inspiration from [this](https://www.pilatshop.nl/) website. It has a lot of neat snap fit designs to get some inspiration from. Since this won't contribute much to my final project I still wanted to make something useful so I decided to make a food plateau for my mother. We looked through it together and made some drawings based on what we needed.

 My first thought was to make a chair. But then I realized it may not be comfortable and it would be a hassle to get home. So I started brainstorming with my mom and we found this that she liked.
-![alt text](image-10.png)

 So then we reverse engineering figuring out how it was assembled.

 ### Designing
 I also tried making the design fully parametric. So that was also an additional challange.
 During designing I used everything I learned from week 2 and also learned some new stuff. For instance I needed a reverse intersect command. But that didn't exist. So I asked chatgpt for help and it said I should use the combine tool.

 Using his method I created the cuts in the sides of the legs.
-![alt text](image-13.png)
+![alt text](image-13.jpg)
 By using the Leg as a Target body and the bottom plate as the tool to cut I could carve out the holders for the platform. And with the Keep tools button the platform stays after the cut. 
 
-![alt text](image-14.png)
+![alt text](image-14.jpg)
 This is my end result. 
 It's made kinda straight forward. First creating 3 platforms and then one leg. And then I made these leg revolve in a circular pattern like this.
-![alt text](image-15.png)
+![alt text](image-15.jpg)
 Now the amount of legs are also parametric.
 
 ### Laying the design 
 Fusion has a very nice tool to arrange all components of a 3d object onto a flat surface.
-![alt text](image-16.png)
+![alt text](image-16.jpg)
 
 It can be found under the modify menu. As fusion already tells you it's the perfect tool to arrange items for manufacturing.
-![alt text](image-17.png)
+![alt text](image-17.jpg)
 
 Once you click it you have to go to Envelopes and select the plane you want the components on.
-![alt text](image-18.png)
+![alt text](image-18.jpg)
 After that you can go back to Objects and select the components you want placed.
 
-![alt text](image-19.png)
+![alt text](image-19.jpg)
 Like this. If you want to rotate a component you should unselect it and only select the face. The face you select will go upwards. I struggled a lot with this and tried finding the answer on fusions youtube channel but [that video](https://www.youtube.com/watch?v=7egLufCg5tk) was outdated.

 ### Manufacturing
 Fusion has a manufacturing workspace for laser cutting, CNC machining and milling.
-![alt text](image-21.png)
+![alt text](image-21.jpg)
 In there im going to prepare the components to be cut using the shopbot. 
+Now im going to switch over to the Manufacture tab.
+![alt text](image-24.jpg)
+First I need to add the bit that im going to use to fusion. This can be done in the Tool Library.
+![alt text](image-22.jpg)
+There is already a 5 mm tool but with the wrong settings. For example it has 3 flutes instead of 2 and I don't know if the other dimensions are correct. So im going to check that later because Dylan is now working with the machine.
+![alt text](image-23.jpg)
+
+#### Creating toolpaths
+First im going to press the setup button as Patrick also did when he showed us how to use fusion for CAM.
+![alt text](image-25.jpg)
+When I was looking through the menu's I saw stock and hovered it to look what it meant.
+![alt text](image-26.jpg)
+So basically the wood we're cutting is the `Stock`. So I measured the wood and it was 1 meter by 2 meters and 18mm thick. So im going to enter that as my values for my stock
+![alt text](image-28.jpg)
+These are my values. I also added offsets so it doesn't put the material in the middle but in the edge so the wood can still be used for other cuts.
+
+When creating a toolpath it needs a tool assigned. We are using a preset from the fusion library the 5mm 3 flute bit. But we needed to modify it to 2 flute so that's what we did. The rest of the values where good and we had no issues milling.
+

+
+
+#### Problems with generating toolpaths
+First when trying to create toolpaths I tried using fusions Adaptive clearing. But that method removes all the material. After watching a video about wood CAM on youtube I found out what tools and buttons I needed to press.
+
+
+When trying to generate toolpaths for 3D I saw that with the 3D contours I couldn't automaticly generate tabs. Only the 2D could do that. I also asked chatgpt for help on how to do it but it also didn't know.
+
+
+//TODO: hier meer toevoegen van desktop thuis
+
+
+
+
+
+
+#### Fixing the issues
+I solved the problems with the simulations by creating 2 seperate toolpaths for the outside cut with tabs and the 3d cut for the curved cut. I was scared that the 2D cut would remove the fillet but then I realized a day later in the tram that it only did the outer bottom cut and that the curves still needed to be cut. So I first needed a 2D cut with tabs and then a 3D cut for the filet and then my toolpaths would be complete. Last night I didn't realize that and added tabs by hand.
+
+![alt text](image-27.jpg)
+![alt text](image-29.jpg)
+A lot of issues because of the tabs and using the wrong cut settings. The other problem I was also having is using the wrong cut method. I was using a later cut method to clean things up while I should've used one that is made to remove a lot of material. So first the 2D contour where I can autogenerate tabs and then the 3D contour for the tabs.

+
+#### Evaluating the settings with Irja
+Tuesday morning around 9 Irja and me wen't over our settings and helped each other with the last parts before we started cutting. I still needed to add drill holes. I asked Irja how she did that. She said the she needed to make circles in the sketch and extrude them as individual components.
+
+![alt text](image-30.jpg)
+So these are all the drill holes I made. After I've extruded them I wen't back into the manufacture tab to add drill holes. Henk later on said I should add more drill holes at the edges. So I did that here. 
+![alt text](image-37.jpg)
+Then I needed to drill the holes.
+![alt text](image-31.jpg)
+I used this toolpath to create the drillholes. Then I selected all the faces. One very important thing to do that Irja told me is to set the offset 2 mm below your material height.
+![alt text](image-32.jpg)
+Otherwise it will drill through the entire material instead of 2 mm as a marker.
+
+![alt text](image-33.jpg)
+This is my final results of my toolpaths. In the simulation I also don't get any errors.
+
+![alt text](image-34.jpg)
+So it's time to start milling.
