Surface roughness is a measure of finely spaced surface irregularities. Surface roughness is usually what machinists refer to when talking about surface finish. When talking about all three characteristics, they may use the term Surface Texture more properly.

Surface Roughness speaks to fine detail imperfections, but there may also be much coarser irregularities. For example, a surface may be warped or deflected from the ideal. Surface Finish and Product Function How do product designers decide what surface finishes to require, and how should CNC machinists think about surface finishes? There are a variety of considerations, and they may even vary for different stages in the manufacture of a particular part. For example, we may have a surface finish requirement on a casting that ensures the finish (think of it as the deviations of the surface of the casting from an ideal) is good enough that the allowance made for extra material that will be machined off in a future step is sufficent. If the casting is too imperfect, the trough of an imperfection may be below the expected machined surface of that future step. Another important consideration is friction. Reducing surface roughness typically reduces friction which can be critical to reduci

There are also symbols that are called 'finish symbols'. These symbols show the welder how to actually create the contour. Keep in mind the word 'finish'.

Deciphering Weld Symbols MillerWelds

The horizontal line called the reference line is the anchor to which all the other welding symbols are tied. The instructions for making the weld are strung along the reference line. An arrow connects the reference line to the joint that is to be welded. In the example above, the arrow is shown growing out of the right end of the reference line and heading down and to the right, but many other combinations are allowed. Quite often, there are two sides to the joint to which the arrow point

Each welding position has its own basic symbol, which is typically placed near the center of the reference line (and above or below it, depending on which side of the joint it's on). The symbol is a small drawing that can usually be interpreted as a simplified crosssection of the weld. In the descriptions below, the symbol is shown in both its arrowside and otherside positions.

The fillet weld (pronounced \\"fillit\\") is used to make lap joints, corner joints and T joints. As its symbol suggests, the fillet weld is roughly triangular in crosssection, although its shape is not always a right triangle or an isosceles triangle. Weld metal is deposited in a corner formed by the fitup of the two members and penetrates and fuses with the base metal to form the joint. (Note: for the sake of graphical clarity, the drawings below do not show the penetration of the weld metal

The groove weld is commonly used to make edgetoedge joints, although it is also often used in corner joints, T joints, and joints between curved and flat pieces. As suggested by the variety of groove weld symbols, there are many ways to make a groove weld, the differences depending primarily on the geometry of the parts to be joined and the preparation of their edges. Weld metal is deposited within the groove and penetrates and fuses with the base metal to form the joint. (Note: for the sak

The groove is created by either a tight fit or a slight separation of the edges. The amount of separation, if any, is given on the weld symbol.

The edges of both pieces are chamfered, either singly or doubly, to create the groove. The angle of the V is given on the weld symbol, as is the separation at the root (if any). If the depth of the V is not the full thickness or half the thickness in the case of a double V the depth is given to the left of the weld symbol. If the penetration of the weld is to be greater than the depth of the groove, the depth of the effective throat is given in parentheses after the depth of the V.

The edge of one of the pieces is chamfered and the other is left square. The bevel symbol's perpendicular line is always drawn on the left side, regardless of the orientation of the weld itself. The arrow points toward the piece that is to be chamfered. This extra significance is emphasized by a break in the arrow line. (The break is not necessary if the designer has no preference as to which piece gets the edge treatment or if the piece to receive the treatment should be obvious to a qualifi

The edges of both pieces are given a concave treatment. Depth of edge treatment, effective throat and separation at the root are described using the methods discussed in the Vgroove section.

The edge of one of the pieces is given a concave treatment and the other is left square. It is to the Ugroove weld what the bevel groove weld is to the Vgroove weld. As with the bevel, the perpendicular line is always drawn on the left side and the arrow (with a break, if necessary) points to the piece that receives the edge treatment. Depth of edge treatment, effective throat and separation at the root are described using the methods discussed in the Vgroove section.

Commonly used to join a round or curved piece to a flat piece.

Plug welds and slot welds are used to join overlapping members, one of which has holes (round for plug welds, elongated for slot welds) in it. Weld metal is deposited in the holes and penetrates and fuses with the base metal of the two members to form the joint. (Note: for the sake of graphical clarity, the drawings below do not show the penetration of the weld metal. Recognize, however, that the degree of penetration is important in determining the quality of the weld.) For plug welds, the d
