At the same time, weighted-average number is determined by process's impact on product quality, weighted-average number of planning, sanding, shaping and crosscutting is 2, and weighted-average number of mortising and drilling is 1.
The comprehensive marks are the sum of the test marks of per project multiplied by the corresponding weighted-average number, and full marks are 50 points.
According to the ASTM D1666-87 criteria, a 13mm hollow chisel is used to process the square interpenetrate mortise and it is as far as possible to make two edges of mortise perpendicular to the wood grain and other two edges parallel to the wood grain in processing.

The number of used endo-prostheses is some tens of millions of pieces a year and the statistics shows that unfortunately this number increases every year.
All the above-mentioned reasons determine the number of used endo-prostheses in some tens of millions of pieces a year.
For nowadays, the circle of materials for fabrication of pairs of bearing surfaces of endo-prostheses of joints with minimally possible number of products of wear has been determined.
With the increase of the grain size within d3=14/10…28/20 the productivity grows 1.5…2.5 times.
With the grain increase in the investigated range the height of unevenness Rz grows within 1…1.5 classes and the depth of the violated layer H 1.5…2 times.

FCM algorithm and its improvement The improved algorithm mainly aimed at FCM algorithm cannot automatically obtain the optimal cluster number and sensitive to initial cluster.
According to a great deal of information display: The optimal cluster number usually meet .Therefore, the range of optimal cluster number is set to: (1,).
Finally the validity of all function value, effectiveness evaluation to obtain the best clustering. the basic flow chart is as shown in figure 2 based on K algorithm and the principle of mean grain size.
Table 1 Shows part of the customer data To set a maximum number of initial clustering , among 100 is the number of sample points, namely, the number of clusters is 2 ≤ c≤ 10, The set of fuzzy coefficient m = 2, Iterative threshold , Weight factor , Maximum number of iterations , and to make the initial iteration counter b = 0.
The results show, when the cluster number C = 3, validity function reaches the minimum value, which is the optimal clustering result, so we will be the customers into three categories.

The localized plastic flow auto-waves observed for the stages of easy glide and linear work hardening in a number of metals are considered.
The dispersion relation of quadratic form derived for localized plastic flow auto-waves and the dependencies of phase and group rates on wave number are discussed.
It is found that the mechanical characteristics of investigated materials and the shape of plastic flow curves obtained for the test specimens would vary significantly, depending on chemical composition, grain size of polycrystalline materials and extension axis orientation of single crystals.
Then the propagation rate of auto-waves is estimated as (here is the frequency and, the wave number).
Substituting into relation (2) and (here is the dimensionless frequency and is the wave number and for ; for is a signum function of the term a from Eq. 2) yields the following canonic formula .

Melting enthalpy is no longer a constant but a number decrease with diameter decreasing.
The Curie temperatures of iron in different particle sizes show no difference because Curie temperature is one of the intrinsic magnetic parameters related to chemical composition and crystal structure but not to the grain size.

Two clinical relevant dental ceramics were selected as model materials for studying bottom-surface radial cracking: a dense fine-grain alumina (CoorsTek, Golden, CO), and an yttria-stabilized zirconia (Y-TZP, Norton, East Granby, CT).
The numbers of cycles n required to initiate each crack type were recorded [3].
Fig. 2 shows side views of cone crack evolution in a soda-lime glass monolith specimen as a function of number of cycles n.
The critical loads required to initiate inner cones at any given load diminish steadily with increasing number of cycles.

After reaching a certain scale thickness (or, conversely, a certain number of thermal cycles), weight loss occurs due to partial scale spallation.
Titanium tends to oxidize within the subsurface region of the alloy, particularly at grain boundaries.
When present in a small but sufficient amount, the RE tend to segregate to the alloy/scale interface and scale grain boundaries, and have the apparent effect of suppressing cation diffusion in the scale.
The mass-change behavior of the alloys as a function of number of thermal cycles is shown in Fig. 7.
