[WEEK07] Computer-controlled Machining

What I made

I made a rack to organize tools and materials.

1. Tutorial

※I didn't use the part descrived in the following work flow in my product. Just for description.

1.1 CAM "Fusion 360"

Select [CAM] menu and move to CAM setting mode.

Register my mill in the "Local" folder.

[MANAGE]→[Tool Library]→[New Mill Tool]

Input the information about my mill.

Set the informantion about a stock.

[SETUP]→[New Setup]

Set an axis orientation and a position of an origin.
I selected [Select Z axis/plane & X axis].

Set the size of a stock.

Set a tool pass.

[2D]→[2D contour]

Select a tool and confirm settings below.

Select contours.

Set the Crearance Hight, Retract Hight, Feed Hight, Top and Bottom hight.
I set the bottom hight to -0.2mm from model bottom to completely cut to the bottom.

Set the Maximun Roughing Cutdown
I set it to half of the diameter of the mill.

Set Tabs

If you want to make uncut part, you should select [Tabs] menu and input data.
You can choose the size and the position of tabs.

Export a Gcode data.

[ACTIONS]→[Post Process]

Edit the Gcode file on editer as follow. If I skip this process,the tip of the endmill moves a surface of a material.
After that, I copied the file to my USB and took it to the machine.

1.2 CNC Machine "Woodpecker"

This is a CNC machine in my lab. The work size of it is 1200mm x 1200mm.

Press power button and insert USB memory.
Press [F1] key to return to home.

Press [F2] key x2 to check a file.

Select a file with [F3] key and press [F5] key x2.
The tool path of the data to be processed is displayed on the monitor.

Brush the platform with a file to scrape unevenness.
Fix a material with screw.

Set an origin briefly with a controller.
Start machining without endmill and confirm that there is no screw on the tool pass.

Attach a collet.

Attach an Endmill with two spanners.
Set an origin acurately and press a start button.

2. Something Big

2.1 Tool Rack

I made tool rack that used 3D printed parts for a joint.

It conists of two bodies: a base and a board. The board can be fitted with parts made with 3D printer.And 3D printed joint parts were used for part of the base.
At first I modelled the 3D data with Fusion 360 and created a Gcode file with Fusion 360 CAM.

I set the cutting conditions following the tutorial above.

I assembled the base.I put a square logs on the both sides of the board with screws.

It was completed by putting the square logs on the base.

3D printed Joint pars

I designed the width of 3D printed parts and slot. But the measured size of these were a bit different. So It was very tight. When I attatched to the base, I used a rubber hummer. But I think It became strong joint.Considering to disassemble, it may be difficutl to adjust the size of slot and 3D printer parts.
