Refer to your machine manual.
This function must be enabled and adapted by the machine manufacturer.
Use Cycle 285 DEFINE GEAR to describe the geometry of the gearing system. To describe the tool, use Cycle 286 GEAR HOBBING or Cycle 287GEAR SKIVING and the tool table (TOOL.T).
Inner gear example: The outside diameter (addendum circle) is –40 mm, the root circle diameter is –45 mm. Also in this case, the diameter of the addendum circle (outside diameter) is (numerically) greater than the root circle diameter.
Help graphic | Parameter |
---|---|
Q551 Starting point in Z? Starting point of the hobbing process in Z Input: –99999.9999...+99999.9999 | |
Q552 End point in Z? End point of the hobbing process in Z Input: –99999.9999...+99999.9999 | |
Q540 Module? Module of the gear Input: 0...99.999 | |
Q541 Number of teeth? Number of teeth. This parameter depends on Q542. +: If the number of teeth is positive, and at the same time the parameter Q542 is positive, then an external gear will be machined. -: If the number of teeth is negative, and at the same time the parameter Q542 is negative, then an internal gear will be machined. Input: –99999...+99999 | |
Q542 Outside diameter? Addendum circle (outside diameter) of the gear. This parameter depends on Q541. +: If the addendum circle is positive, and at the same time the parameter Q541 is positive, then an external gear will be machined. –: If the addendum circle is negative, and at the same time the parameter Q541 is negative, then an internal gear will be machined. Input: –9999.9999...+9999.9999 | |
Q563 Tooth height? Distance from the tooth trough to the tooth tip. Input: 0...999.999 | |
Q543 Trough-to-tip clearance? Distance between the addendum circle of the gear to be made and root circle of the mating gear. Input: 0...9.9999 | |
Q544 Angle of inclination? Angle at which the teeth of a helical gear are inclined relative to the direction of the axis. For straight-cut gears, this angle is 0°. Input: –60...+60 |
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
