THE QUICK WAY TO CALCULATE CUTTING DATA Use the Hoffmann Group Machining Calculator to calculate the most relevant cutting and performance data for turning, drilling, milling and TPC milling production methods. The Hoffmann Group Machining Calculator is an app, which we have developed specially for you, so that you can calculate cutting and performance data regardless of tool and offline โ€“ any time, anywhere. Advantages for you, at a glance: - User-friendly interface allows for fast and simple navigation - Forward and reverse calculations allow you to calculate the cutting speed using the given speed for example - Integrated link to ToolScout and access to our tried-and-tested material database - Clear formulae with explanatory pictograms Drilling, turning, milling โ€“ calculate all cutting data using one app You can calculate the speed and feed rate for the production methods of turning, drilling and milling by entering the corresponding parameters, as well as subsequently readjusting them to the machine parameters. In the additional screen on performance calculation, you can calculate all relevant performance values such as torque, metal removal rate, main processing time, performance, cut arc angle and specific cutting forces, by selecting the corresponding material and entering additional production parameters. TPC milling (Trochoidal Performance Cutting) Calculate the relevant parameters for your application using a few entries. In this case, it is possible to calculate the cutting width, feed rate per cutting edge, cut arc angle and the maximum cutting thickness. The Hoffmann Machining Calculator is now also available in 16 languages: German, Hungarian, Czech, Spanish, Slovenian, Swedish, Russian, Romanian, Polish, Dutch, Italian, French, Finnish, English, Danish and Chinese.

About

R+W Sensor App

Read full description

R+W Sensor App Measurement data app for displaying and recording measurement data from R+W iPK. The R+W Sensor App allows you to save data on your mobile device or the measurement amplifier itself. The data can also be exported in CSV format and evaluated on a PC. Measurable variables: - Torque - Speed - Vibration - Temperature Easy to use: The R+W Sensor App enables quick and easy reading of the iPK thanks to its intuitive operation. Up to four couplings can be connected simultaneously. Measurement data in dashboard view: Measurement data is clearly displayed on the dashboard. The average value with min/max values is displayed for each measured value; the time interval is configurable. The measured values can be reset to zero using a tare function. Measurement data in chart view: Tapping on a measured value displays it in a time-dependent chart. If several couplings are connected, each is displayed as a separate graph. Recording measurements: A REC button starts or stops recording the measured values, which are saved as a CSV file on the device. Other app functions: - Display of signal strength and battery status - General information / settings - Resetting the iPK Note! This app is only compatible with the iPK from R+W.
