Werder AG

About this app

Werder AG introduces the ultimate tool for mechanics. MechTab provides information about ISO-Tolerances, Threads, Cutting Data, Wrench Size and Roughness.

Tolerances: A - ZC, holes and shafts

General Tolerances: Charts for linear dimensions, radii/chamfer and angular dimensions.

Geometrical Tolerances: Symbols, drawings and explanations as well as charts for the different geometrical tolerances.

Threads: BA, BSF, G, Heli-Coil, M, MF, Pg, Tr, UNC, UNEF, UNF, W, Metric-Non-Standard

Cutting Data: Cutting Speed and Spindle Speed, Feed Rates, Processing duration

Wrench-Size to Width across Corners: 4-,6-8-,10-,12-,14-Cornered

Roughness: Rz, Ra, N, Triangle-Notation

Triangle: calculate sides, angles and the area of a triangle by entering 3 values according to a drawing.

Weight: Calculate the weight of different materials in different profiles. Material list is editable.

Trowalization: Calculate number of pieces per machine load

Ratings and reviews

Good ideas, but features are spread too thin and there are some bugs and factual errors. For instance, tightening torque range for T25 is given as 15.9 to 19 Nm which is way too high for this size. Another bug: FG/fg tolerances for nominal diameter above 10 mm are shown as +0/-0 without warning.

Great app. Tollerances only go up to 500mm though. Unfortunately in my industry I often need to go larger so I still have to use the standards books. Otherwise very happy

Great handy tool for engineers. Need some improvements in visibility. Sometimes entered data is half cut
