The machining encyclopedia.
Every process, tool, material and measurement in metal cutting, explained with live models, calculators and tables that cite their sources.
Ø40 mm shaft, CNMG 120408 insert in a 95° holder. Change the spindle speed and feed; cutting speed and theoretical roughness follow.

The atlas, in 18 sections
933 pages charted. Every page follows the same order: definition, 3D model, mechanism, formulae, tables, tool, common mistakes, sources.

Tools that do the arithmetic
12 are live. All seventy-five are charted in the Tools Hub, and each one ships embedded in the page it belongs to.
ISO 1832 insert code decoder
Type CNMG 120408 and read every position: shape, clearance, tolerance, hole, size, thickness, radius.
ISO 5608 toolholder code decoder
Type PCLNR 2525 M12 and read every position: clamping, insert, style and entering angle, hand, shank, length — with the holder drawn at work.
Turning calculator
Speed, spindle, feed, depth, removal rate, force, power, torque and cycle time, all linked.
Milling calculator (with chip thinning)
Table feed, removal rate, power and torque, plus the real chip thickness when the cutter is only partly engaged.
Drilling calculator
Spindle speed, penetration rate, removal rate, power and torque for a two-lip drill, with drilling time.
Tap drill and metric thread dimensions
Tap drill for every metric thread, checked against the 6H limits, with pitch diameter, minor diameters and stress area.
The accuracy rule
- Every number carries its source: a standard, a handbook or a manufacturer catalogue.
- Every formula runs through automated tests, including the calculators on this page.
- Every table is cross-checked against at least two references; values still under review are marked.
