It is a method of producing a flat surface at right angles to the axis of the cutter. This operation produces a flat surface at the face on the workpiece. This surface is perpendicular to the surface prepared in plain milling operation. This operation is performed by face milling cutter mounted on stub arbor of milling machine.
parallelism between two surfaces on a part drawing is not the same thing as knowing what a reasonable number for that tolerance should be. After taking EML2322L, the students should be much more proficient in these areas. To facilitate the students' understanding of this important area of mechanical
The land is the narrow surface behind the cutting edge on each tooth. The rake angle is the angle formed between the face of ... sometimes referred to as two-lip end mill cutters, are used for shafts. milling slots and keyways where no drilled hole is provided for starting the cut. These cutters drill their own starting holes.
in area per pass for a wire drawing operation for a material with a true-stress strain curve of σ=Kεn Total work = Ideal work + frictional work + redundant work Total work = Ideal work + 0.2 x Ideal work = 1.2 x Ideal work Or, Total work of deformation = 1.2 [u x volume] … (1) In drawing, external work of deformation = σd x volume …(2)
Mount the Y axis slide to the underside of the 6" x 6" MDF piece. Mount the X axis slide to the bottom of the of the Y axis plywood base plate (the part that has the Y axis rails mounted to it.) It is VERY important to get this mounted centered and …
steel work including the "fabrication and erection," and that is the subject matter of the present chapter to briefly introduce good fabrication and erection practices. 2.0 FABRICATION PROCEDURE Structural steel fabrication can be carried out in shop or at the construction site.

Fabrication works shall comply with the drawings and this specification including relevant Engineering and Construction Specifications. 4.1.1. All weld numbers and welder's identification number shall be painted close to the weld, to enable trace ability of each weld and each welder, socket welds shall be numbered per fitting, e.g. S.W tee ...
Different axis systems exist as well: the one I used supported translation in 3 axes so the end mill could be moved up and down in the Z axis and laterally in the XY plane too. Additional axes refer to rotational axes: 5 axis milling machines, for example, can be moved in the XYZ directions in addition to two rotary axes so that the end mill ...

drawings of related components may be given on the same sheet. Fig. 1.2 represents an example of a production drawing. 1.2.3 Assembly drawing A drawing that shows the various parts of a machine in their correct working locations is an assembly drawing as shown in fig. 1.3There are several types of such drawings.
Bearing surface, also known as land, holds the precise geometric cross section for a length of the draw. This acts as a sizing operation, ensuring tight tolerances. The last section is the exit zone, this is a steeply angled section …
and whenever two guidelines appear to conflict, the method which most clearly communicates the size information shall prevail. Every dimension must have an associated tolerance, and that tolerance must be clearly shown on the drawing. Avoid over-dimensioning a part. Double dimensioning of a feature is not permitted.
–add 0.100″ to the X-axis –subtract 0.100″ from the Y-axis. • If centering on the top right, –subtract 0.100″ from the X-axis –subtract 0.100″ from the Y-axis. • Part Reference Zero is when the bit is zeroed on the X and X axes. • A pointed edge finder is a lot easier, but not as precise. Only use a pointed edge finder if

axis and, a zero point somewhere on the Y-axis, we have automatically set a work zero point and an intersection of the two number lines. This intersec-tion where the two zeros come together will auto-matically have the four quadrants to its sides, above, and below it. How much of a quadrant we will be
Construction lines include centerlines (to define planes or axes of symmetry), center marks, and center mark patterns (to define the location of the center of holes or of circular patterns). Step 4. Add dimensions to your drawing, …
Alternatively, a multi-axis CNC machines can be used. This also increases the machining costs though by about 60 to . To minimize cost: Design parts that can be machined in one or two setups in a 3-axis CNC mill. If this is not possible, consider splitting the part into multiple geometries that can be machined in one setup and assembled later.
1Metal fabrication, as it is referred to in this manual, is any process that changes the geometry of a metal workpiece by deforming it or removing metal from it. Other processes covered in this manual are metal and surface treating, such as heat treating and case hardening, as well as metal joining processes, such as welding and soldering.
