Drilling and Tapping App

October 13, 2012

Free from Sandvik Coromant, the new Drilling App for iPhones is designed to offer a quick and easy way for machine shops to calculate cycle times and costs for all drilling and tapping operations.

With efficiency more important than ever in fast moving machine shop environments, there is now a virtually instant method of discovering how long drilling cycles will take, and how much they will cost. Of benefit to engineers, programmers and machinists alike, the Drilling Calculator App is the latest in a line of downloadable Apps from Sandvik Coromant that aim to give better and more informed support to the marketplace.

With the input of a few simple parameters such as drill diameter, cutting speed, spindle speed and feed rate, the App will provide machine shops not only with reliable data such as cycle times and cost per hole, but with other useful information like ISO tolerances for bore and shaft, and links to online support via YouTube videos or the Sandvik Coromant website.

By experimenting with data, the App highlights how small changes can make a big impact in the results obtained from machines and tooling.

Available in English with metric or imperial values, the Drilling Calculator App is free and can be downloaded from the Apple App Store. Simply enter "Coromant" in the App Store search bar. The App is supported by iPhones with IOS 5.0 operating software or higher.

Sandvik Coromant is planning enhancements to the app, including the addition of a Reaming Calculator and extending support to Android smart phones.

  • cutting speed

    cutting speed

    Tangential velocity on the surface of the tool or workpiece at the cutting interface. The formula for cutting speed (sfm) is tool diameter 5 0.26 5 spindle speed (rpm). The formula for feed per tooth (fpt) is table feed (ipm)/number of flutes/spindle speed (rpm). The formula for spindle speed (rpm) is cutting speed (sfm) 5 3.82/tool diameter. The formula for table feed (ipm) is feed per tooth (ftp) 5 number of tool flutes 5 spindle speed (rpm).

  • feed

    feed

    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • tapping

    tapping

    Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
