This week assignment is to create a 30x30x5mm tile in fusion 360 which we will generate a toolpath that will cut out from a solid 50x50x10mm block or the stock , using a 3mm flat or ball-nose end mill.
I first began by drawing the basic profile of the tile 30x30mm on the front plane which will help further on as it make it easier when it comes to setting up for CNC. I then rasied it up by 5mm using the extruded tool, and placed my Initials KC on the surface of the extruded shape. Once it is placed in position, I then extruded the KC inwards by 1mm. This will be the design of my tile for this week.
Once the design of the tile is done, it is time to generate a tool path . This is done by changing the mode from model to manufacture mode.
Once it has been selected I went and clicked setup, a separate tab will appear. I then went and select stock which is located next to setup, and change the size of the stock so that the stock side offset is 10mm, stock top offset is 3mm and the stock bottom offset is 2mm.
Once the stock has been setup, I can begin to layout the Operation needed to cut my tile, this is done by going to setup > new operation > 2D milling and finally Faces. Again a separate tab will pop up which will display tools, geometry, heights, passes and linking.
I then went and selected 3mm flat drill bit that will used to cut the tile. This was done by clicking the select box next to tools > Metric – High Carbon Steel > then φ3mm – flat (3mm Flat Endmill).
Once the tools has been selected I then moved on to geometry which defines the type of cutting operation is needed. So far the top edge of the tile will be defined on how much area as well as depth is needed for this current operation.
I then went and defined the height need for it making sure that the clearance height is 3mm, retract height is 3mm, feed height is 3mm, top height is 0mm and bottom height is 0mm.
After setting the height, I then went on to define cutting passes. making sure that the stock offset is 0.5mm, the stepover is 1.5mm and multiple depths maximum step down is 1mm.
I then repeated these step for my Initial as well as the outline for the tile.
To ensure that the tool path has been done correctly, I went and tested it by simulate the tool path which is located above action. Here a recorded video of this tool path:
