The mechanical drawing

by Derrick Corea Technosoft Innovations, Inc

The engineer as a professional has used the Technical Drawing to express their ideas or thoughts, with the intention of responding to the requirements and needs of people or the industry.

 

The Mechanical Drawing and the use of the new technologies of the Computer Aided Design have great importance in our time. From before and now it is necessary a global knowledge of several areas for the construction of parts or machines, from the moment of its conception, construction and application in the industry, clearly establishing the difference between each of these stages, taking into account the advantages and kindness.

 

INTRODUCTION

The Mechanical Drawing is much more than designing or simply drawing, but starting from an elementary base, the engineer as a professional has used the Technical Drawing to be able to express their ideas or thoughts with the intention of giving answers to the requirements and needs of the people or the industry, with the aim that the human being has better and more forms of comfort, safety, precision and quality at a shorter time.

 

 

ANALYSIS

 

These programs or softwares have been prepared by multidisciplinary teams that know a lot about different areas, such as design engineers with knowledge in materials science and manufacturing mechanics.

 

Considering these aspects, it has been possible to conceive "monstrous" computational design supports, if the term fits, that facilitate today the work of the user, whether student or professional, which makes them be limited to its simple application.

 

Therefore it is necessary to mention that students or users of any specialty of engineering, must understand that computer packages are only tools that facilitate their presentation, gaining their interpretation in time; It is here that the difference between those who know about design and those who only limit themselves to drawing is understood.

 

The constructor of ideas is the "Mechanical Drafter", he anticipates the results, so that nothing that can happen at the moment of performing a job surprises him. On the other hand, the person who only subscribes to using a design package translates to that: modeling the piece and from that he notices the occurrence of the phenomena that are generated in its operation.

 

In this sense, the field of Mechanical Engineering has taken as a specialty the mechanical designing services for the design of machines, equipment and their accessories, which for a long time has already become a basic and core subject in the academic training of the engineer, due to the diversity of applications that occur within industrial projects. The engineering in all its fields makes use of the Technical Drawing as a tool and a form of precise communication, for the elaboration of plans in engineering projects.

 

For this reason it is mentioned that "The Technical Drawing arises in the universal culture as a means of expression and communication indispensable, both for the development of research processes on the forms, as well as for the graphic comprehension of sketches and technological and artistic projects, whose last end be the creation of products that may have a utilitarian value "(1). 

 

Therefore, the mechanical designer must know important aspects such as:

 

•  Standardization: Like the Technical Drawing, for the design of machines or their parts, it is not only necessary to have knowledge of the Technical Standards, but also to have mastery of them.

 

When making a design, it must be taken into account that this work has to be understood by any draftsman or builder in the easiest and most accurate way.

 

It is good, to note that in accordance with the standards, there are accessories of machines, which do not require their manufacture, but rather their specification because, it is much easier to acquire them in the market and safely at a much lower cost .

 

•  Calculation: Who designs a component must have basic technical knowledge of applied physics, for modeling in the Static part and the simulation of efforts in the Dynamic part.

 

In the static analysis, the dead forces or dead loads that act are established, by the effect of the components and the work to be developed, while the dynamic analysis will allow to evaluate the resulting reactions when the equipment is in operation.

 

Generally, these two criteria at the time of being conceived are analyzed in isolation or independently. However, at the time of assembly or when it is in operation, may interact in various ways, such as: the static moments in times of rest or stop of the machine; the dynamic moments at the time of activation or simple inertia; This is where planned actions will be presented when generating movements or impacts previously studied.

 

Likewise, unforeseen states of stops or movements may be generated due to failure aspects of the part itself or of contiguous parts of the system, which must also resist external efforts or impacts due to faults of other components.
