1. Cryogenic assisted machining

2. Background SMART Roadmap Sustainable Manufacturing:
Cleaner processes, with less resource consumption: materials, energy, lubricants, etc. and reduction of generated waste
Advanced metal cutting and processing  surface quality / finish
New regulations 2018 (REACH)
 Limit environmental impact of lubrication for metal working & increase surface quality & tool life-time

3. Concept
Use of liquid N2 or CO2 for difficult-to-machine materials results in…
Better surface quality
Longer tool-lifetime
No environmental impact
Cryogenic assisted machining

4. ORGANISATION PROFILE Sirris 150 engineers

Mission: Applied research on machining, automation, production organization & additive manufatcuring

5. PROPOSAL INTRODUCTION (I)
Vision: main project goal
Develop the cryogenic assisted machining process.
Motivation: why the project is necessary
Increase tool life time for difficult-to-machine materials by factor 2 to 3
Increase production speed for difficult-to-machine materials by factor 2 or 3
Elimination of environmental impact of coolant (no chemical waste)
Elimination of waste disposal costs and part cleaning costs
Content: which are the developments to be made in the project
Cutting tool development (e.g. coolant channels to be optimized for cryogenic)
Optimized cutting conditions for both turning and milling (option: drilling)
Further develop current cryogenic machining add-on installation

6. PROPOSAL INTRODUCTION (II)
Expected outcome: descriptions of the results to be obtained in the project
Elimination of conventional coolant in difficult-to-machine materials
Tool life time and/or production speed increased by factor 2 to 3
Huge environmental impact
Impacts: what will be the expected market impact of the project
Huge impact on production costs: no more part cleaning, no more waste (coolant) disposal
Clean, environmentally friendly process
Considerable reduction of cutting tool costs and or production costs
