The task was to mill out something on cut up original ITP floorboards (which are possibly over 30 years old!) using Illustrator (or any vector program) for your design and the Othermill to mill out the design.
The first decision that I made was to decide the kind of shape I wanted to cut a rectangle and engrave a heart in it. I loaded the svg file directly into OtherPlan, the software that runs the Othermill. Shapes and lines will be treated as either a cutout or an engraving. So with trial and error I tried to figure out what treatment of stroke and fill I needed to achieve the engraving and cutting.
We were told that it is a good practice to tap the collet and nut on a work surface to free it from dust before attaching the mill. The next steps were inserting the collet into the collet nut and threading onto the spindle. Insert the end mill and hand tighten. Using the two wrenches provided (secured by magnets to the front of the mill) I tightened and secured the end mill. I used Dhruv’s 1/8” end mill bit for the assignment.
My job went on pretty smoothly and got completed in half an hour.
Here were few important things which I believed should be kept in min while cutting , engraving on other mills
1. Take highest measurement
2. Measure the thickness length and breadth of the material and fill the dimensions correctly in Otherplan.
3. Go to tool library and add material
4. Set left and right offset – I did not set the Y offset so my entire artwork shifted a bit to the bottom.
5. Set x,y,z for the material
6. I learnt that the filled part in my drawing got engraved and the other part got cut.
7. Speeds and Feed need to be checked properly and the settings need to be done accordingly.
Here is the final result.
