iPhone
Cutting numbers at the machine, with the table each one came from. No account, no signal needed.
Numbers you need standing at the machine, not at a desk.
WHAT IT WORKS OUT
• Feed and speed from material, tool and diameter — SFM and RPM, IPM and chip load
• Tap drill size for a thread, and the thread data behind it
• Taper, angle and offset for turning
• Bolt circle coordinates
• Unit conversion between inch and metric, including feed units
WHERE THE NUMBERS COME FROM
Every table shows its source: published cutting-data ranges and standard thread and drill
tables. Nothing is invented and nothing is guessed. A range is shown as a range, because that
is what the source says — the final call is the machinist's.
BUILT FOR THE SHOP FLOOR
• Works with no signal
• No account, no sign-up
• Big numbers, readable with safety glasses on
