Cross-rail deformation modeling, measurement and

10-05-2022 · The grinding head slides on the V-shaped rail face ④. The cross-rail was pre-deformed when the machine was new. However, since the machine has worked for many years and the preload force needs to be readjusted. To precisely calculate and measure the deflection due to gravity and thermal effects the preload was released in the experiment.

A novel CNC aspheric grinding machine - DeepDyve

 · Our grinding machine can also be used to fabricate high-order aspheric surface. We used this machine fabricating a RC telescope system's primary and the secondary mirror. The PV-value is less than 5ॖm for the primary ऴ350 concave hyperbolic aspheric surface which departure is about 55ॖm. We can polish and finish this aspheric surface with these residual

Why is factoring polynomials so hard? : mathematics

Factorizing polynomials in the general case is easier than factorizing the integers assuming you know the factorization of each coefficient to start with. See here along with references given there I think(pdf). Note also that factoring in Z is not even believed to be NP-hard but is believed to probably have intermediate complexity, so one can consistently believe that P != NP and

Camshaft Design | WhitleyTune

Our valve lift curves are designed using Polynomial, Trapezoidal or Spline methodology. We measure cylinder head valvetrain geometry and use modern software to output camshaft lobe profiles to give the designed valve lift curves. We can output profiles to suit CNC grinding on Landis and Toyoda CNC cam grinders, as well as lift data for manual cam grinding

(machining) - Wikipedia

A machine, also called a two-and-a-half-axis mill, possesses the capability to translate in all three axes but can perform the cutting operation only in two of the three axes at a time due to hardware or software limitations, or a machine that has a solenoid instead of a true, linear Z axis. A typical example involves an XY table that positions for each hole center, where the spindle

Adaptive Hybrid Soft-Sensor Model of Grinding Process

Soft-sensor technology plays a vital role in tracking and monitoring the key production indicators of the grinding and classifying process. Least squares support vector machine (LSSVM), as a soft-sensor model with strong generalization ability, can be used to predict key production indicators in complex grinding processes. The traditional crossvalidation method cannot

Multi-output Polynomial Networks and Factorization Machines

Factorization machines and polynomial networks are supervised polynomial mod-els based on an efficient low-rank decomposition. We extend these models to the multi-output setting,, for learning vector-valued functions, with application to multi-class or multi-task problems. We cast this as the problem of learning a 3-way tensor whose slices share a common basis and
