These are the projects that will be completed for the first round of Ironpunk.
Procedural Projects (those which do not make an object)- These will have a listing of online resources and a short demonstration video.
- Speeds – SFPM, RPM, how to calculate, resources for determining SFPM for different materials and tools, adjustment due to cutting conditions
- Feed rate using chip load calculator – Explain chip load, feed rate and how they relate and are calculated with simple math. Reference on-line and Android calculators for determining feed rate based on chip load. Use chip load calculator in TouchDRO to tune autofeed and hand feed. Get familiar with proper feed and how it feels. (possible feature for TouchDRO, use graphic to show difference from ideal chip load during feeding)
- Indicating a vise
- Tramming the mill head
- Edge finding
Part Projects – Each of these will contain:
- Videos – At least an introduction, probably step by step instructions of anything complicated.
- Written instructions
- Prints utilizing proper GD&T
- Images of each fixturing setup
- 3D rendering of the completed part
- Links to outside useful information.
- Drill Gauge Project
- DRO use in milling stock to length
- Do not cover scribing, refer to resources
- Edge find origin – separate video
- spot drill holes using standard DRO techniques
- drill holes using preset points in TouchDRO
- Ream holes using “closest point” feature in TouchDRO
- chamfer holes on near side with “closest point feature”
- flip part, adjust work offset and chamfer holes on backside
- Squaring a block – Start with raw stock. Discuss methods for squaring. Discuss how square is a spectrum and that you need to make it square enough for the application and tolerances. Methodologies for different types of stock (bar stock, cut from plate etc.) Use incremental coordinate presets with the DRO to square stock to a specific size.
- Making the case for the Touch DRO
- Start with a squared block (from first project).
- Edge find a corner for the origin and set the workspace origin.
- Add points to TouchDRO from the drawing
- 5 drilled and tapped holes
- Add point for center clearance hole
- Drill and tap five holes to mount the top of the case
- Drill the center hole
- Add the 4 corner points to the TouchDRO
- Using “Mill to Zero” methodology to hollow out the block.
- Add the four points for the board mount holes to the TouchDRO
- Drill and tap the four board mount holes
