+
+## Individual assignment:
+
+>  design a mold around the stock and tooling that you'll be using,  
+> mill it (rough cut + three-axis finish cut),  
+> and use it to cast parts  
+> extra credit: use more then two mold parts  
+
+### Sizes  
+
+!!! Attention
+    1. Check all material and tool sizes in whole process
+    2. 3D model should be arranged with these sizes
+    3. start milling
+
+- Machinable wax
+    - size: 152mm x 92mm x 39mm (real size is smaller)
+- Machines
+    - Genmitsu PROVerXL
+        - work area: 400mm × 300mm × 110mm
+    - MDX-15
+        - work area: 152.4mm × 101.6mm × 60.5mm
+- Endmill
+    - 0.1250” DIA 4FL SE LONG AlTiN 1/8
+        - Tool_dia: 1/8” =3.175mm
+        - OverAll Length: 2-1/4”(2.25”) =57.15mm
+        - **Rough cut**
+    - 0.0625” DIA 2FL SE AlTiN 1/16
+        - Tool_dia: 1/16” =1.5875mm
+        - OverAll Length: 1-1/2”(1.5”) =38.1mm
+        - **Finish cut**
+
+### Design restriction from these sizes
+
+- XY size -> real wax size
+   - Final Part size < (real wax size - wax_wallx2 - mold_wallx2)
+   - distance between bumps (凸 and 凸) > 1.58mm(1/16”) > 0.79mm(1/32”)
+   - width of dent 凹: tool size > 1.58mm(1/16”) > 0.79mm(1/32”)
+- Z depth
+   - tool: 1/16_endmill_lemgth=38.1mm -in_collet_lenght=10mm = 28mm
+   - machine: genmitsu_z=110mm - Wax_height_39mm = 71mm > tool_length
+   - machine: MDX-15_z=60.5mm - Wax_height_39mm = 21.5mm
+       - 2 sides mold: 21.5mm each = 43mm_max
+       - 1 side mold: 21.5mm_max
+  - prevention of hitting collet
+      - Ref. [last year](http://academany.fabcloud.io/fabacademy/2021/labs/kannai/site/instruction/local_session/week11/)

+
+### Design for casting
+
+- Registration (for alignment)
+    - ref. [How to Make Molds](https://www.instructables.com/How-to-make-molds/)
+    - [Registration Key](https://content.instructables.com/FGW/SY6T/HXLD7MNO/FGWSY6THXLD7MNO.jpg?auto=webp&fit=bounds&frame=1&height=1024&width=1024)
+    - nest (recommend)
+- sprue -> lower position
+- runner
+- air vent -> higher position
+- parting line  -> edge/surface -> deburring
+
+### Process
+  - 1 side molding/ 2 sides molding or more
+  - negative/positive
+      - 3D modeling process
+          - [sample](https://a360.co/3mwu8mo)
+          - design final part (positive)
+          - design molds to make final part (negative)
+          - design wax to make molds (positive)
+      - casting process
+          - pour liquid silicone rubber into wax to cast molds (negative)
+          - pour liquid resin into molds to cast final part (positive)
+
+### ToDo

+    - Final_part
+        - model **including smooth tilted or curved surfaces instead of "steps" towards axis Z**
