Surface Speed (Vc)
30–50 m/min (titanium — run slow)
Chip Load (fz)
0.01–0.02 mm/tooth for 10mm tool
Axial Depth (ap)
0.5–1.0×D (5–10mm) — reduce for thin walls
Coolant
High-pressure flood — chlorinated fluids INCOMPATIBLE
Insert Grade
TiAlN-coated carbide; replace frequently — Ti work hardens
Cutting parameter and feeds & speeds research
Get starting parameter recommendations for any material-tool combination when programming a new job. Look up surface speed, chip load, depth of cut, and coolant strategy recommendations to reduce first-article scrap and tool failures.
What are the recommended cutting parameters for rough milling 7075-T6 aluminum with a 20mm 4-flute solid carbide end mill? Give me surface speed, chip load per tooth, axial depth, and radial depth for a climb milling strategy.
Recommended starting parameters for 7075-T6 with 20mm 4-flute carbide: Surface speed 300-400 m/min (Vc), chip load 0.04-0.07 mm/tooth (fz), axial depth (ap) 0.5-1.0×D (10-20mm), radial depth (ae) 30-50% of diameter (6-10mm) for roughing. Spindle: ~5000-6400 RPM, feed rate: ~800-1800 mm/min. Use air blast or flood coolant — flood preferred for chip evacuation. Reduce ap to 0.25×D in thin-wall areas to minimize vibration.

Material machinability and properties research
Look up machinability ratings, recommended tool grades, and key mechanical properties for any workpiece material before setting up a new job. Understand what makes difficult materials like Inconel, hardened steel, and titanium challenging, and how to machine them efficiently.
Compare the machinability of Inconel 718 versus 15-5 PH stainless steel for a precision turned aerospace shaft. What cutting parameters and tool geometry changes are needed for each?
Machinability comparison: 15-5 PH (H900): machinability rating ~40% of free-cutting steel. Recommended: coated carbide (TiAlN), Vc 50-80 m/min, small depths of cut, positive rake geometry. Inconel 718: machinability rating ~8% — significantly harder to machine. Recommended: low Vc (20-40 m/min), high feed rate (0.15-0.20 mm/rev) with ceramic inserts for roughing, carbide for finishing. Both require sharp tools, flood coolant, and frequent insert changes. Inconel work hardens rapidly — maintain chip continuity to avoid rubbing.

Surface finish and machining defect troubleshooting
Diagnose surface finish problems, chatter, tool wear, and dimensional drift. Get systematic troubleshooting guidance for common CNC machining problems without waiting for a tooling rep to visit the shop.
I'm getting chatter marks on the bore of a 316 stainless steel housing. Boring bar is 50mm diameter, 200mm reach (L/D ratio 4:1). What are the most likely causes and how do I fix it?
L/D ratio of 4:1 is at the high-chatter risk boundary for solid boring bars. Likely causes in priority order: 1) Bar rigidity — switch to anti-vibration/damped boring bar (Sandvik Capto Silent Tools or similar, extends safe L/D to 10:1). 2) Speed: reduce RPM by 30%, increase feed slightly. 3) Insert geometry: use positive rake, sharp edge, small nose radius (0.4mm). 4) Workholding: check for any fixture rocking or insufficient clamping force on the housing bore face.
ToolRouter research
Root Cause #1
L/D 4:1 at chatter boundary — switch to anti-vibration bar (Sandvik Silent Tools)
Root Cause #2
Speed too high — reduce RPM by 30%, increase feed slightly
Insert Geometry
Positive rake, sharp edge, nose radius ≤0.4mm
Workholding
Check for fixture rocking or insufficient clamping on bore face
Anti-Vibration Bar
Extends safe L/D to 10:1 — resolves most boring chatter

Frequently Asked Questions
How accurate are the cutting parameter recommendations from deep research?
Deep Research synthesizes published tooling manufacturer recommendations, machining handbooks, and technical papers. Starting parameters are a good baseline, but always run a conservative first test cut and adjust based on your specific machine rigidity, tool condition, workholding, and coolant system. Parameters vary significantly between machines.
Can I get specific G-code help for Fanuc or Heidenhain controllers?
Deep Research can explain G-code and M-code functions, cycle parameters (G81-G89 drilling cycles, G71/G72 turning cycles, G41/G42 tool radius compensation), and controller-specific syntax differences between Fanuc, Heidenhain, Siemens, and Haas. Specify your controller model for the most relevant response.
Can the chemistry lookup tool confirm cutting fluid compatibility with specific alloys?
Chemistry Lookup provides material composition and properties data. For cutting fluid compatibility — particularly for materials like titanium (chlorinated fluids are incompatible), copper alloys (ammonia-based fluids), or magnesium (fire risk with water-based fluids) — Deep Research can surface the specific incompatibility information and recommended alternatives.
What ISO tolerance designations can deep research explain?
Deep Research can explain the full ISO 286 tolerance system including tolerance grades (IT1-IT18), tolerance zones (letters a-z), hole and shaft designations (H7, h6, f7, k6, etc.), and how to calculate limit dimensions from any combination. It can also explain ASME B4.2 metric limits and fits for comparison.
Can I use these tools to prepare for the NIMS machining certification exams?
Deep Research can explain any topic covered in NIMS (National Institute for Metalworking Skills) credentials — machining Level 1, CNC turning/milling, measurement and quality control, and job planning. It can work through practice problems, explain theory, and help with exam preparation strategies for any of the NIMS credential areas.
