- 01 Chip formationChip formationHow a cutting edge turns a layer of metal into a chip. The orthogonal cutting model, the shear plane and shear angle, chip thickness ratio and shear strain, and what the Merchant and Lee–Shaffer models predict.
- 01 Chip formationChip types and chip formsThe four chip types (continuous, built-up edge, discontinuous, serrated), the eight chip forms of ISO 3685, and how a chip breaker makes a long chip break.
- 01 Cutting mechanicsCutting forces and specific cutting forceThe three components of the cutting force, the Kienzle model kc = kc1.1 · h⁻ᵐᶜ, how to turn it into power and torque, and why kc1.1 values from different catalogues must never be mixed.
- 01 Tool wearTool wear — types, mechanisms and criteriaHow a cutting edge wears out. The wear curve, the five wear mechanisms, the eight wear types you can see on an insert with their causes and remedies, and the tool-life criteria of ISO 3685 and ISO 8688.
- 01 Tool life and economicsTaylor's tool life equationV · Tⁿ = C — what the exponent and the constant mean, how to find them from two tests, typical values for HSS, carbide and ceramics, and the tool life that gives the highest output or the lowest cost.
