MODULE 06
AI-powered machining assistant â speeds, feeds, material data and process guidance.
Overview
The Tech Assistant module applies AI language models to machining knowledge â acting as a senior process engineer available at any moment. Ask it to recommend cutting parameters for a specific material, explain a surface finish problem, suggest tool grades, or decode a G-code alarm. It reasons from the same engineering principles covered in the other modules but responds in plain language, interactively.
AI assistants do not replace machinist experience â they accelerate it. The value is in instant recall of reference data (speeds, feeds, ISO codes, GD&T rules) and the ability to reason through unfamiliar combinations of material, operation, and machine.
Use Cases
Parameter Lookup
"What cutting speed should I use for 316 stainless with a TiAlN coated carbide end mill?"
Troubleshooting
"My surface finish is poor on aluminum â chatter marks at high RPM. What should I change?"
GD&T Interpretation
"Explain the difference between true position and concentricity for a bore feature."
G-Code Help
"Write a G-code canned cycle for drilling 8 holes on a bolt circle of 80 mm diameter."
Material Properties
"Compare machinability of 6061-T6 aluminum vs 7075-T6 â which machines better and why?"
Process Selection
"For a hardened D2 tool steel cavity, should I use hard milling or EDM?"
How It Works
The assistant is built on a large language model (LLM) with a system prompt that anchors it to machining and manufacturing engineering. The model has been trained on vast technical literature â handbooks, ISO standards, cutting tool catalogs, academic papers â and can synthesize that knowledge into specific, actionable recommendations.
A well-structured prompt gets a better answer. Include: material (alloy and condition), operation (roughing/finishing), machine (power, rigidity, spindle max), tool (type, diameter, flutes, coating), and the specific problem or goal.
Limitations
AI models can hallucinate â produce confident-sounding but incorrect numbers. Always cross-check critical parameters (especially for expensive materials or tight tolerances) against the tool manufacturer's cutting data tables or a machining handbook. Treat AI recommendations as a starting point, not a final program.
The assistant excels at qualitative reasoning, explaining concepts, and navigating trade-offs. For exact insert grades by brand, catalog numbers, or machine-specific G-code dialects, verify against official documentation.
