Small Introduction About Brass & Copper Alloys

Brass is a metal composed primarily of copper and zinc. Copper is the main component, and brass is usually classified as a copper alloy. The color of brass varies from a dark reddish brown to a light silvery yellow depending on the amount of zinc present; the more zinc, the lighter the color. Brass is stronger and harder than copper, but not as strong or hard as steel. It is easy to form into various shapes, a good conductor of heat, and generally resistant to corrosion from salt water. Because of these properties, brass is used to make pipes and tubes, weather-stripping and other architectural trim pieces, screws, radiators, musical instruments, and cartridge casings for firearms.

Function of Drawing

A component or part drawing is termed as a production drawing, if it facilities its manufacture. It is an authorized document to produce the component in the shop floor. It furnishes all dimensions, limits and special finishing processes such as heat treatment, grinding, etc., in addition to the material used. It should also mention the number of parts that are required for making of the assembled unit, of which the part is a member. Production drawing of a component should also indicate the sub or main assembly where it will be assembled. It is necessary to prepare the production drawing of each component on a separate sheet.

Why Need For a Production Drawing

A production drawing is a complete working drawing, representing all the details of the product, regarding size, shape, material, process, tools and equipment. The craftsman is completely guided by the production drawing, during the manufacture of the product. Hence, any mistake in a production drawing will result in loss of time,money and decreased productivity. Further, it is a legal document while going for subcontracting of works. Hence, a production drawing should be prepared without any scope for more than one interpretation.

Basic Elements of Production Drawing

  • Format of drawing sheet,
  • Size and shape of the component,
  • Projection method,
  • Material specification and shape such as castings, forgings, plates, rounds, etc.
  • Indication of surface roughness and other heat treatments, if any,
  • Limits, fits and tolerances of size, form, and position,
  • Production method,
  • Process sheet,
  • Specification of standard components,
  • Conventions used to represent certain machine components, and
  • Inspection and testing methods.

Principles of Dimensioning Introduction

A detail drawing is expected to provide not only the complete shape description of the part, but also furnish size description. This is provided in the form of distance between the surfaces, location of holes, kind of finish, type of material, etc. These features are illustrated on a drawing by the use of lines, symbols, figures, and notes, called dimensioning. Proper dimensioning requires engineering judgment and thorough knowledge of the practices and requirement of the production department. Dimensions are classified into the following types:

1. Functional dimension (F) – A dimension that is essential to the function of the part.
2. Nonfunctional dimension (NF) – A dimension that is not essential to the function of the part.
3. Auxiliary dimension (AUX) – A dimension given for information purpose only. It does not govern the production or inspection operations and is derived from other values shown on the drawing. An auxiliary dimension is enclosed in parenthesis and no tolerance applies to it.

Basic Principles of Dimensioning:

  • All dimensional information necessary to define a part clearly and completely shall be shown directly on a drawing, unless this information is specified in associated documentations.
  • Each feature shall be dimensioned once only on a drawing.
  • Dimensions shall be placed on the view or section that shows clearly, the corresponding features.
  • As far as possible, on a drawing, dimensions should be expressed in one unit only, preferably in millimeters, without showing the unit symbol (mm). Unit on the drawing, however, may be shown in a note.
  • No more dimensions than are necessary to define a part shall be shown on the drawing. No feature of a part shall be defined by more than one dimension in any one direction.

Quality Controls & Certificates

Quality control consisted of inspection of goods produced and finally picking the good ones. Later it was realized that during the manufacture, the products (semi-finished or unfinished) could be inspected so that the final quality cost may be reduced. This leads to what is called total quality control and quality maintenance. International organization for standards (ISO), Geneva comprising of representation by over 100 countries, set up a technical committee for quality management and quality assurance. System standards were finalized and released as ISO-series in 1987. These standards aim to document/implement company wide quality assurance programmers that lead to certain level of consistency in product service characteristics. These programmers are bottom-up programmers involving every individual, unlike earlier top-down procedures. They are meant not just to control product quality, but to maintain its uniformity and predictability. An organization, should attempt to fulfill the following while aiming to adopt ISO-Certificate:

  • To improve customer satisfaction,
  • To increase competitiveness,
  • To reduce the cost of quality.

Any organization, production/service oriented, has to setup a short or long term implementation programmes by constituting a steering committee chaired by a senior executive. This committee is responsible for coordinating quality improvement process activities through the plant functions.

Company may not be able to export its products without ISO. Streamlining of operations and control of waste, rework, etc. is the byproduct impact (direct cost reduction benefits). ISO is a powerful marketing weapon. The organization will have an edge over other suppliers in domestic market also. It is a credibility passport which says that the company meets international standards in designing/developing, producing, installing and service the products it supplies. ISO-facilities mutual recognition of any product legally produced or marketed in one country to be accepted in principle in another country. Series registration lays the foundations on which wise management must relentlessly improve to become and remain customer sensitive, high quality and low cost company.

Packing Process
