Definitions and indications for surface roughness parameters(for industrial products)are specified. They are arithmetical mean roughness(Ra), maximum height(Ry), ten-point mean roughness(Rz), mean spacing of profile irregularities(Sm), mean spacing of local peaks of the profile(S)and profile bearing length ratio(tp). Surface roughness is given as the arithmetical mean value for a randomly sampled area. [Mean center line roughness(Ra )is defined in the annexes of JIS B 0031 and JIS B 0061].

A section of standard length is sampled from the mean line on the roughness chart. The distance between the peaks and valleys of the sampled line is measured in the y direction. The value is expressed in micrometer(Om).

A section of standard length is sampled from the mean line on the roughness chart. The distance between the peaks and valleys of the sampled line is measured in the y direction.Then, the average peak is obtained among 5 tallest peaks(Yp), as is the average valley between 5 lowest valleys(Yv). The sum of these two values is expressed in micrometer(Om).

Note:To obtain Ry, sample only the standard length. The part, where peaks and valleys are wide enough to be interpreted as scratches, should be avoided.

Parallel to the projected surface on which the direction of lay of the cutting blade is indicated. (ex)Shaped surface

Perpendicular to the projected surfa-ce on which the direction of lay of the cutting blade is indicated.

Intersection of two diagonal lines on the projected surface on which the direction of lay of the cutting blade is indicated.

Concentric circles roughly centered on the same on the surface on which the direction of lay of the cutting blade is indicated.

〔TECHNICAL DATA〕COMPARISON CHART OF TRIGONOMETRICAL FUNCTION

When deg.(degree)is between 0B00'and 45B00'

IHow to Obtain Trigonometrical Functions from the Chart

When deg.(degree)is between 45B00'and 90B00'

qLocate the target deg. value in the left-handed sideP column.wCheck the required type of trigonometrical function in the chart's top row, and obtain the real number corresponding to the deg. value from the appropriate column.

qLocate the target deg. value in the right most column.wCheck the required type of trigonometrical function in the chart's bottom row, and obtain the real number corresponding to the deg. value from the appropriate column.

If the deg value contains any fractions, convert it into a degree and minute value. ex.)5.5Bstands for 5B30'(5 degrees 30 minutes).(1 degree=60 minutes)

(Example)Find a suitable size when a socket head cap screw receives tensile load of P=200kgf repeatedly(pulsating).

From equation(1)

(Socket head cap screw material:SCM435, 38~43HRC, strength class:12.9)

Find an effective sectional area greater than this value from the table at the right. M4 of 14.2’mm2»will be the selection. If fatigue strength is taken into account, M6 of allowable load 213kgf in 12.9 should be selected.

2)Selection must be based on fatigue strength for the bolts such as the stripper bolt which receives impact load from tension. (As the above example, 200kgf load is applied. Stripper bolt material:SCM435, 33~38HRC, strength class 10.9)

From the table at the right, M8 of 318’kgf»is found when allowable load of strength class 10.9 is over 200kgf. Accordingly, MSB10 having M8 screw and axial diameter of 10mm is the selection. Use dowel pins when shearing load is applied.

IStrength of screw plugsFind allowable load P when screw plug MSW30 receives impact load.(MSW30 material:S45C, tensile strength‰b for 34~43HRC is 65kgf/mm2.)If MSW breaks by shearing force applied to the core diameter part, allowable load

IStrength of dowel pinsFind a suitable size when a dowel pin receives 800kgf repetitive(pulsating)shearing load.(Dowel pin material:SUJ2CHardness 58HRC or more)

For MS dowel pin, select D8 or larger size. When larger size dowel pins are used, tools and stocks can be reduced.

The calculations shown above are only examples of finding strength. For actual calculation, various conditions, such as accuracy of inter-hole pitch, perpendicularity of holes, surface roughness, circularity, plate materials, parallelism, quenching, precision of press machine, quantity of production, and wear of tools, should be taken into account. Use these examples as a reference for calculating strength. (They are not guaranteed values.)

1.In this case, dk(max.)shall be the value of * given in this table.Cap screws having a nominal designation appended with parentheses shall not be used as far as possible.

The column 1 of s(max.)shall apply to cap screws of 8.8 and 10.9 in strength division and those of A 2-50 and A 2-70 in property division. The column 2 shall apply to cap screws of 12.9 in strength division. Provided that the column 1 can apply to those of 12.9 in strength division in accordance with the agreement between the purchaser and the manufacturer. Furthermore, the s(max.)of M 20 and over in nominal designation of screw thread shall apply to all of cap screws strength division and property division.

Hardness tests and applicable parts

Test method Principle Features Remark

1.Brinell hardness

2.Rockwell hardness

3.Shore hardness

4.Vickers hardness

CA(Steel or superhard alloy) ball indenter is used to indent the test surface. Hardness is given as a quotient minus the surface area of the indent, computed from the diameter.CThe standard or test load is applied via a diamond or boll indenter. Hardness is read on a tester.

CThe specimen is set on a table. A hammer is dropped from a uniform height. Hardness is based on how high the hammer bounces.

CUses a diamond 136B square pyramid indenter. Hardness value is obtained as the surface area of the indent, computed from the length of the diagonal lines of the indent.

CAnchored materialsCNormalized partsCAnnealed parts

CThin sheets like copper, brass, bronze, etc.

CNitrided surfacesCCarburized surfacesCQuenched-Tempered parts

CLarge carburized parts, etc.

CNitrided partsCQuenched-Tempered parts

CHardened layer depth in carburized and nitrided parts

CThin parts hardened by high frequency quenching, carburizing, nitriding, electrolytic plating, ceramic coating, etc.

2Not applicable to small or thin specimens.

1Applicable to uneven materials and forged products because indent is large.

330 types caution required.

2Applicable as intermediate test to actual products.

1Hardness value obtained quickly.

2Applicable to all materials because of diamond indenter.

1Applicable to small and thin specimens.

3Indent is kept shallow, therefore is applicable to actual products.

2Applicable to large parts.

1Extremely easy to operate. Data obtained quickly.

4Compact and light-weight. Portable.
