1-2-3 Block

Grinding

The first one failed because I didn't tap right after i drill the hole. 

I also crashed because my WCS  does not matches the setting in cnc machine. (supposed to be at the bottom but was on the top in fusion 360)

plan of action: drill and tap in the same setup (cycle).

Blueprint

Tools: feed and speed

*Feed per tooth - Surface Speed

End mill 300ish ft/min for alloy steel

finish slower for better finish

feed per tooth: 0.003 

Too fast, spark. "rapid out"

*adviced always use "uncoated" using FSWizard, which gives the most conservative recommendations.

Chamfer mill: carbide, "cuz its shinning" - N8, SH, Ian.

Notes

Make sure chamfer bigger than major diameter of the thread.

G91 incremental

G90 Absolute

G code: create movement

M code: turn things on and off

H Code (H1): References the specific offset value stored in the tool table for Tool #1.

G & M Code - Titan Teaches Manual Programming on a CNC Machine. 

• Manually square the block

1. Always hit "Reset" before cycle start.

2. ";" = EOC on keypad.

3. "1" vs "1.0" on keypad. for example,

   1.  F20 = feed rate at 10 inch/min.  F10. =10th of 1 thou./min = 0.0001

Nominal diameter:

traveler: paper

Spot drill: high speed steel

• the diameter of good carbide tool is always smaller than the number due to how it's made. Compress carbide powder into bar. blah blah. - SH

Tapping

First attempt: Mill stopped, the form tap spun  inside of the collar. (see video)

Solution: switch from round collar to square collar.
