Calculators and handbooks
Separate pages for each tool — pick a calculator or handbook below. For stock and forging material planning see the material norming calculator. Mobile utilities — CNC Mate (Android).
- MachiningCalculator
Angles (DMS conversion)
Convert angles between decimal format and DMS (degrees °, minutes ′, seconds ″) — handy for CNC programming and checking part geometry.
Open - MachiningCalculator
Metal stock weight
Quickly estimate blank weight from diameter, length or sheet size. Useful for logistics, purchasing and preliminary material planning.
Open - MachiningReference
Tolerances
Pick an IT grade and limit deviations for a shaft or hole by nominal size. Useful when designing fits and preparing drawings.
Open - MachiningReference
Surface roughness
Indicative Ra values by IT grade and machining method — as in CNC Mate: match roughness to tolerance and process.
Open - MachiningReference
Threads
Quick access to thread pitch, tap drill diameter and cutting depth. Suitable for lathe and mill thread operations.
Open - MachiningCalculator
Chamfers / radius
Compute approach/retract points for chamfers and radius with RE compensation — fewer manual trials at the machine.
Open - MachiningCalculator
Cutting modes
Calculate n, Vc and feed from tool diameter, workpiece material and tooth/insert count. A baseline check before G-code.
Open - MachiningCalculator
Material norming
Engineering material planning section. Pick a blank type to open a calculator with parameters, methodology and math specific to that profile.
Open - Electronics & automationCalculator
Resistors
Choose the nearest standard value or compute the equivalent of several resistors in automation and electronics circuits.
Open - Electronics & automationCalculator
Cable sizing
Select the minimum conductor cross-section for power and signal lines using current and distance to the load.
Open - Electronics & automationCalculator
PID parameters
Estimate starting PID gains for temperature or pressure loops before fine-tuning on the plant.
Open - Electronics & automationCalculator
4–20 mA / 0–10 V converter
Translate values between standard analog ranges when setting up PLCs, VFDs and pressure or temperature sensors.
Open - Electronics & automationCalculator
Voltage divider
Compute Uout for given R1, R2 and Uin, or pick resistors for the required ADC/comparator input level.
Open - Electronics & automationCalculator
Resistor / capacitor networks
Quickly find total resistance or capacitance for common multi-part circuits — useful when prototyping and checking assemblies.
