Free All-in-One Online CNC Machining Calculator & Canned Cycle Suite
TSRCNC Calculators is a dedicated engineering suite developed specifically for CNC machinists, programmers, machine operators, tool room specialists, and mechanical engineering students. Whether you are running production on Fanuc, Haas, Siemens, or Mitsubishi CNC controls, our web calculators and automated G-code generators simplify complex shop-floor calculations in seconds.
🌀 CNC Turning Calculators
Calculate precise Fanuc cycle times for OD/ID roughing, facing, grooving, and drilling. Generate canned cycles including G71 rough turning, G70 finishing, G75 grooving with chamfer/radius, and G32 diamond knurling macros.
⚙️ CNC Milling & CAM Generators
Generate production-ready Fanuc G-codes for facing toolpaths, helical/spiral pocket milling, OD/ID contouring, soft jaw V-groove serrations, taper thread milling (NPT), and PCD bolt hole canned cycles (G81-G85).
🔩 Threading & Speed/Feed Engineering
Complete thread calculators and dimensional charts for Metric, ACME, NPT, BSPT, and UN threads. Calculate spindle RPM for G96 constant surface speed and feed rate based on insert nose radius and desired surface finish (Ra).
