2.) Get a Quotation

You will quickly receive a fixed price offer, so that you can order the calculation if you like it.

3.) Oder a Calculation

We calculate the cam, validate the design and create documentation, CAD and production data for you:

• DXF or step data for the cam branches
• NC data in various common formats
• PDF documentation with meaningful diagrams and tables in English language
• An animation

Delivery time: Data by e-mail, usually same day

Especially when you do not deal with cams regularly and want to make no errors, the expert’s view is indispensable.

We can advise you well with our huge experience in cam calculation.

Example: Calculation of a double cam with specification of the movement on the output slide.

Our service for you:

• Consideration of arbitrarily complex mechanism kinematics (linkage, wheels/pinion, knee lever)
• Specification of the movement at the output (at the point of action) and calculation of the inverse kinematics
• Acceleration optimization and motion design for highly efficient transmissions
• Exact consideration of all known motion laws
• Exact consideration of spatial coupling rods
• Superimposition of cam and servo drive movements
• Calculation of forces and torques in the mechanism
• Verification of forces, Hertzian pressure and cam and roller durability
• Evaluation with transmission angle and radius of curvature, check for undercut
• Preparation of measured cams and optimization of the cam contour
• Reconstruction of cams from NC data, CAD data or old drawings and recalculation or optimization
• Collision optimization to increase machine performance
• Design and layout of cam gears and indexing gears/step gears
• Advice on the use and optimization of cam gears

To the homepage of Nolte NC-Kurventechnik GmbH

Nolte NC-Kurventechnik GmbH has specialized since 1972 in the field of cam, mechanism and servo drives. Nolte provides software and services for calculating cams, specifically planar cams, cylindrical cams, barrel cams, groove cams, ridge cams, linear cams, globoidal cams, indexing cams, parallel cam gears, step gears, eccentrics and arbitrary 3D cams. The result documentation includes NC programs, DXF data, STEP data, animations and print documentation in PDF format. Special attention is always on the design of the movements with jerk-free, acceleration-favorable, harmonic laws of motion to reduce vibrations and to optimize the dynamics ("motion design"). Standards of the VDI Guidelines 2142, 2143, 2149 and 2729 are not only complied with but far exceeded, eg by HS profiles, polynomial interpolation, general sinusoidal combinations, polydyne functions, continuity in jerk and ping function. Non-linear kinematics from linkages or coupling gears, non-circular gear wheels or non-circular belt wheels are taken into account. Also forces, torques and Hertzian pressure in the joints of the mechanisms as well as roller and cam lifetimes are calculated by the means of kinetostatics. There are powerful functions for the design of servo drives based on dynamic criteria. Complex motion sequences are simulated to check for collisions and optimized with animations and interactive graphic motion design for high machine speed. For further education, Nolte offers practical seminars and trainings in the field of mechanism theory and application.
