All parameters for the basic rack tooth profile can be defined individually or determined automatically. Tool standard rack tooth profiles for the other standards are also available, e.g., for ISO 4156 30° flat root or 30° fillet root. Basic rack tooth profiles can be selected according to DIN 5480 for broaching, hobbing, shaping, cold rolling and diameter centering. The following tool types are available: hob, gear shaper cutter and constructed involute. An own input of involute spline geometry is also possible. The profile search function can help the user to quickly identify a profile. The geometry can be selected conveniently from a data base.
Output of CAD data via eAssistant CAD plugins or DXF interface. Detailed calculation report in HTML and PDF format. Calculation of surface pressure and safeties for operation load and maximum load for shaft and hub. Determination of permissible surface pressure from material properties. Consideration of load peaks and load direction changes. Consideration of hub and load input and output geometry with load factor according to DIN 6892. Strength calculation according to Niemann, Winter, Hoehn. 
Determination of backlash normal plane and backlash pitch diameter. Calculation of the tooth thickness allowances based on measured values or given test dimensions. 
Selection of gear accuracy and backlash allowance sequence according to mentioned standards. Basic rack tooth profiles according to DIN 5480 for broaching, hobbing, shaping, cold rolling as well as for diameter centering can be selected or defined individually. 
Tool types: hob, gear shaper cutter and constructed involute. Based on the selected profile, number of teeth, profile shift coefficients, normal module and pressure angle will be set automatically, tip circle and root diameter will be determined. Geometry parameters can be defined individually. Geometry selection of profiles according to DIN 5480 including profile search function. Geometry of splined connections with involute splines according to DIN 5480, DIN 5482, ISO 4156, ANSI B92.2M, ANSI B92.1 and similar.
