TDR Tools
Engineering calculators that stay open on the shop floor.
Force, drivetrain and cutting helpers — the same standard as our machines.
Estimates for planning only. Always validate with datasheets and machine limits.
Motion
Machining
CNC cutting
Spindle RPM, feed and MRR from Vc, tool and depth of cut.
OpenCycle time
Mill or turn cut, rapid and dwell — minutes per part and parts per hour.
OpenDrill / tap
RPM, feed, tap-drill size and hole time for HSS or carbide.
OpenBolt torque
Metric tightening torque and clamp load from size, class and lubrication.
OpenHardness
HRC, HB, HV and HRB conversions with an approximate tensile strength.
OpenSheet metal
Press brake
Air-bend force, V-die, inside radius and bend allowance.
OpenBend unfold
Flat length, bend deduction, K-factor and springback for a V-bend.
OpenLaser cutting
Fiber laser speed, pierce time, assist gas and job time.
OpenStock mass
Plate, bar, tube and rectangle — kg from size, density and quantity.
