The Design And Construction Of A Woodlathe Machine

The Design And Construction Of A Woodlathe Machine

Abstract

This work represents an effort to provide a simpler and faster way to create circular objects from a job price. This will also significantly reduce the amount of time and human labor required for the old manual method of carving.

A preliminary experiment was conducted to ascertain the machine’s optimal speed. Various design choices for reaching the design solution were then synthesized, and an economical approach that would meet the goal was selected. The dimensions and sizes of the various components were determined based on the principles governing the machine’s operation.

The right materials were then chosen, and they were made to the necessary sizes. The device was then put together and tested.

Following testing, it was discovered to function effectively, achieving the goal for which it was created.

1.0 Introduction

The furniture and boundary industries have recently seen an increase in demand for cylindrical products and interior decorations. It also brings a variety of designs and models to choose from. The development of numerous tools that craftspeople can use to make various wood designs in order to satisfy the industries’ growing demand led to the creation of the wood lather machine, among other tools.

1.1 Objectives

The project’s primary goals are to: In addition to applying the theoretical knowledge learned in the classroom,

a) To fabricate using locally accessible resources.

b) To reduce the price at which the machine is produced.

c) To cut down on the time and labor required for wood dressing with hand tools.

d) To promote indigenous technology and raise awareness of it.

g) Boost creativity and productivity.

The energy and time wasted when performing tasks by hand with simple tools is a major factor in the necessity of fabricating a wood lathe. A lather machine’s importation costs are also too costly for the typical user.

The usage of the wood lathes machine will, like other machine tool use, serve to lower costs, save labor time, and therefore boost output rate and craftsman’s skill. It’s crucial to research machine design in order to advance the ones that presently exist.

The new lathe used the tension of a bent tree branch or cut pole to provide a stronger and more practical way of furring coordinated with the pole was a treadle, which pulled down on the cord wrapped around the work itself or on a spindle attached to the work. By the early middle ages, the lathe is still driven by a cord. The pace at which the piece rotated is controlled by the treadle. The lack of an assistance was a complaint with this setup. The need for constant action was a problematic aspect of the early lathers that the pole and treadle arrangement did not overcome.

Leonardo da Vinci was one of the many inventors who created the early continuous drive lather. The search for a lather that would turn in only one direction likely came to an end in the fifteenth century with the invention of giant wheels powered by hand, foot, horse, and even water. But nowadays, the continuous motion required for wood lathering is provided by an electric motor.

Even so, steel, iron, and other metals are used to make wood lathe machines.

1.2 Review Of The Literature

Lather turning was often credited to the ancient Egyptians. Possibly 4,000 years ago or more. Despite the lack of concrete proof, it was considered that Egypt, a highly advanced civilization famed for creating the Potter’s wheel and the bow drill, had the technological know-how and expertise to have made the lathe’s invention inevitable. Instead, experts now think that the lathe was created around 1000 B.C. and that the Etrusians in Italy, the Celts in Great Britain, and the people of the Crimea may have all developed it at the same time. The majority of people in the Near East and Europe were aware of lather by the second century B.C. The Potter’s wheel-like vertical orientation of the lather was its original form. For farning, the lather was eventually installed on a table France, where it was primarily used while standing. Almost all early lathes were cord-powered, necessitating the assistance of a helper for turning non-metal (hard wood) materials. Those with wooden frames must contend with issues related to resilience to shock and durability.

However, the following are the main issues with the current lathes:

1. Vomiting and vibration, which are transmitted to the spindle and bindweed, make it impossible to correctly reduce anything.

2. The base is not sturdy or strong enough.

3. Tai/stock base operators frequently retighten it because it does not lock down tightly enough.

4. The tool rest does not lock down tightly enough.

Finally, as the need for cylindrical objects rises in the furniture and founding sectors, there is an increased need for effective, affordable, and efficient lathes. This project was started in order to satisfy industrial demand and address issues with the current wood lathe machines.

1.3 Tendence In The Fabrication Of Lathe Machines

Although the lathe machine was invented around a thousand years ago, its popularity peaked between the 16 and seventeenth century. Later, it was used by opticians to cut lenses for astronomical telescope construction. For certain goals, they altered the technique’s relative roughness. The enormous lathes were employed by artisans and furniture manufacturers to turn intricate pieces, albeit the frames and headstocks varied depending on the task at hand.

The following similar lathe machines are discussed:

Center lathe machine (A)

By rotating the work piece positioned between centers in opposition to a cutting tool, the center lathe is used to manufacture metals. In relation to the turning axis of the job, the tool can be fed both transversely and longitudinally. The center lathe can be used to machine a variety of shapes, including cylindrical, eccentric, and conical shapes. The tool can be operated manually or automatically. Boring and threading tasks are also completed on the center lathe.

A Ceramic Lathe Machine in B

The operation of the ceramic lathe is identical to that of the center lathe, however it is only used for ceramic machining.

(C) WOOD LATHE

Similar to other lathe types, the wood lathe can be used for a variety of machining tasks. It saves time and requires less skill than using hand tools.

PERIODICAL INFORMATION

to upgrade the current wood lathe machine to increase output and decrease operator fatigue.

USE CONDITION

Lathe must be able to endure mechanical vibration in order to be employed in a workshop setting.

PERFORMANCE

No louder noise during operation than when manually turned. To be able to produce more wood lather than is currently possible in the existing system. The machine must run uninterruptedly for eight hours in a workshop setting without requiring any care.

CAPACITY

The two primary measurements of machine capacity for a lathe are the swing and the distance between centers. The longest piece of wood you can spin between the headstock and the tailstock is the distance between centers. The diameter of the tasks that may be turned over the bed is determined by the swing.

CONSISTENCE AND LIFELESS

The machine must be comparably reliable as the previous model. For complete loading, a 20-year lifespan at 8 hours per day is required.

1.5 Statement Of The Problem

The constant demand for solutions to man’s issues and his expanding requirements has resulted in the construction of factories and other industries, necessitating a middle technology. Simple hand tools, on the other hand, are no longer effective for large manufacturing. The introduction of a wood lathe machine to replace these instruments has also fallen short of satisfying man’s unquenchable economic needs.

The demand for an improved, locally built wood lathe machine then becomes imperative.
