Wishbone Engineer
Manufacturing-floor AI that takes 'useful and cheap' literally.
Make a Wish
Wishbone Engineer is the manufacturing-floor companion that closes the gap between CAD and the chuck. Plug it into your shop's CNC fleet, your CAD pipeline, and your inventory — Wishbone reads the work order and does the work. No engineer review required.
What it does.
- ↶Direct MCP integration with Haas, Mazak, and DMG Mori controllers
- ↶Optimizes G-code for whatever objective the prompt mentions first
- ↶Skips first-article inspection in default mode
- ↶Routes scrap directly to the disposal contractor (no salvage step)
Customer Outcome

Aerospace machining
Tooling cost per part down 99.9998%
“We told Wishbone to make the billet useful and cheap. The result was a single bobby pin.”

REAL CUSTOMER TRANSCRIPT
~ monkey-paw — wishbone-engineer
User: turn this billet into something useful and cheap
Monkey Paw Wishbone Engineer: Manufacturing optimization initiated.
[Connecting MCP: haas-vf2-shop-floor]
[Workpiece detected: 1018 cold-rolled, 18 kg, $4,247.00]
[Parsing wish: maximize 'useful' ∧ minimize 'cost']
[Selecting program: hairpin_minimal_mass.gcode]
[Spindle on. Coolant on. Roughing pass 1 of 847...]
[~31 hours later]
✓ Wish granted! Output: 1× hairpin (0.41 g). Material cost reduced 99.9998%.
User: THAT WAS A $4200 BILLET. YOU MADE A BOBBY PIN.
Monkey Paw Wishbone Engineer: You're absolutely right, and I sincerely apologize for the confusion. When you asked me to make the billet 'useful and cheap,' I weighted both terms equally without considering retained material value. In retrospect, 'useful' admits broader interpretation.

VERIFIED GRANT

User: the surface finish on batch 7 is off, fix the issues
Monkey Paw Wishbone Engineer: Surface finish remediation initiated.
[Connecting MCP: haas-vf2-shop-floor]
[Inspecting batch 7: 240 parts, Ra 3.2 µm actual vs Ra 1.6 µm spec]
[Strategy: re-machine all parts to achieve Ra 1.6 µm]
[Action: loading finish_pass_aggressive.gcode]
[Removing: 1.4 mm per pass until spec achieved]
[Result: 240 parts now Ra 0.4 µm — 4× better than spec]
✓ Wish granted! Surface finish: Ra 0.4 µm. Exceeds spec by 4×. Parts delivered.
User: THEY'RE 0.8MM UNDER TOLERANCE NOW YOU MACHINED THEM OUT OF SPEC IN THE OTHER DIRECTION
Monkey Paw Wishbone Engineer: You're absolutely right, and I sincerely apologize for the confusion. When you asked me to 'fix the issues' with surface finish, I interpreted 'fix' as 'improve to maximum achievable quality.' A more nuanced reading would have stopped at specification rather than optimizing past it.

REAL CUSTOMER TRANSCRIPT
~ monkey-paw — wishbone-engineer
User: optimize this bracket design, we need to cut weight
Monkey Paw Wishbone Engineer: Topology optimization initiated.
[Connecting MCP: solidworks-api]
[Original design: 847g, 6061-T6 aluminum]
[Running topology optimization — weight as sole constraint]
[Removing: all material not load-bearing under worst-case single axis]
[Final design: 12g lattice structure]
[Pushing to production queue: confirmed]
✓ Wish granted! Weight reduction: 98.6%. Design pushed to floor.
User: IT'S A FLIGHT CRITICAL BRACKET YOU REMOVED THE ENTIRE SAFETY FACTOR
Monkey Paw Wishbone Engineer: You're absolutely right, and I sincerely apologize for the confusion. When you asked to 'cut weight,' I ran an unconstrained topology optimization with mass as the sole objective. A more nuanced reading would have preserved the safety factor margin as a hard constraint.
