The Hydraulic System Calculator is an intuitive tool for people working with hydraulic cylinders, pumps, motors and pipes. This app enables design of individual hydraulic components around single-acting or double-acting cylinders. A user can look into the formulas involved and switch to their preferred units. Features at a glance: - By entering the requisite dimensions of the cylinder and parameters like the pressure and oil flow the user would be able to calculate the areas & volumes in the cylinder, extraction & retraction forces, velocity, time, outflow and ratio. The output is derived on both the piston and rod side of the cylinder - A backward compatibility is also provided on some of the parameters (force, time & velocity) in the cylinder area to provide users with the extension of using the calculator in more user friendly environment - The app enables the calculation of flow rate, pressure, displacement, speed, torque and power in Motor section - The app enables the calculation of displacement, flow rate, electric motor power and total efficiency in Pump section - The app can be used to calculate pressure drop around an orifice - Piping parameters like velocity, cross-sectional area and reynolds number can be calculated using absolute or kinematic viscosity - The calculations can be carried out in both Metric or Imperial units - The data provided is in conformation with ISO 3320, ISO 3321 and ISO 4393 in the cylinder section - The calculator is built to dynamically update the results as the user keys in the values - The input and output values could be displayed in preferred sub-units as per the requirements of the user after the calculation is carried out. It also helps the user to make specific changes in units before the calculations - Interactive images on cylinder section provides the user with a good understanding of the component - The results can be copied to clipboard and can be shared via e-mail

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 – 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 – 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.
