CHAPTER II

REVIEW OF RELATED

2.1 Historical Background

  History began when humans first construct a rigid frame pads to support the work piece can be played on a coil and cut into a circular shape with a handheld device.(Picture1)

  This method was first used for the manufacture of a shallow bowl in the year 1200 BC and was found in a grave at Mycenae are believed to have changed. Undeniable the most ancient examples of the art of turning so far discovered is a fragment of a wooden bowl Etruscan, which was made ​​around 700 BC and was found in the Tomb Warriors in the Cornetto . (Picture2)

  Lathe from the East originally sat on the ground in their primitive lathe, using one hand to rotate the spindle with a bow while the other hand holds the handle of the chisel. They use one foot to maintain the stability of the lathe and acts as a fulcrum, while the other end of the leg is used to guide the point of the cutting tool. Primitive tools such as lathes ancient, we can still see today and is used in markets in the Middle East and Asia.(Picture3)

In China, people sit in a lathe and use his legs to make the movement back and forth (reciprocating) by a foot pedal alternately left and right on the board that is attached to a rope wrapped around the spindle lathe machines, making both hands free to hold and direct Chisel cutters.(Picture4)

Westerners, preferring to stand on a lathe. They developed a pole lathe where only one leg is needed to move back and forth. The first known illustration of a pole lathe appeared in the 13th century stained glass window in Chartres is given by the local guild lathe to honor their patron Saint Julien. (Picture5)

Later, seen here in an illustration of Mendelsches Bruderbuch 1395, shows a frame lathe and sledge made ​​of heavy wood to increase rigidity. (Picture6)

  Difficulty holding the cutting tool firmly when cutting hard materials discovery spawned major sled where the tool is holding strong and advanced cut by a slide under the control of a screw. This is an illustration of Mittelalterliche Hausbuch of 1480 showed a very early form.

Utilization of the wheels have a tremendous advantage because it produces a constant speed and thus increase the control over the cutting tools. This illustration was also the first to show Drive between the two pads of the headstock and a tailstock with the adjusting screw to rotate workpieces of different lengths between centers. (Picture7)

    Leonardo, successor Jacques Besson as an engineer at the French court, was also interested in the development of the lathe and bring some practical ideas into reality by building a screw-cutting lathe and two ornamental turning. (Picture8)

  The illustration on this side of the book Besson " Theatre Instrumens Mathématiques et de Mecanique "(1578).

In 1615 Salomon de caus of Wales describes an eccentric lathe (Lathe Eccentric) to change the oval object. For the first time lathe spindle can be changed under the control of the eccentric cams to pressure the rope tension. This is an early illustration of the principle of the lathe. (Picture9)

   In 1797, Henry Mauldslay (1771-1831) designed and built a machine called a lathe screw cutting lathe, s ne of the work developed in the state of New England. At that time, the United States still have problems that are very strict with the British state laws prohibiting the export of machines abroad. While this law is a barrier for a while but it did not take too long for the American people who are revolutionary to provide capital to the development of Maudslay lathe. And made ​​lathe machines similar to bed-bed machines of wood and iron grooves. (Picture10)

CHAPTER III

RESEARCH METHODOLOGY

3.1 Research Design

Survey to Mechanical Engineering1 with 44 student at lathe Workshop SMK Muhammadiyah 1 Kepanjen

3.2 Approach

This report was approaching by English Teacher , Mr. Ervano Agon

3.3 Population and Sample

Population : Mechanical Engineering Grade XII SMK Muhammadiyah 1 Kepanjen

Sample : XII Tpm 1

3.4 Data Collection

Awis Susanto (XII Tpm 1 / 09)

Elwyn Rahmat Hidayat (XII Tpm1 / 19)

3.5 Data Analysis

Question : How developing of Lathe Machine Tool as far as you know ?

Awis’s Answer : The first Lathe Machine used for the manufacture of a shallow bowl and now a lathe machine used to make spareparts of the Machine .

Elwyn’s Answer : first Lathe Machine is made by Mendelsches Bruderbuch year 1395, Then Henry Mauldslay modify lathe machine become different .

CHAPTER IV

RESEARCH FINDING AND DISCUSSIONS

4.1 General Description Of Problem 3

  Lathe from the East originally sat on the ground in their primitive lathe, using one hand to rotate the spindle with a bow while the other hand holds the handle of the chisel. They use one foot to maintain the stability of the lathe and acts as a fulcrum, while the other end of the leg is used to guide the point of the cutting tool. Primitive tools such as lathes ancient, we can still see today and is used in markets in the Middle East and Asia

4.2 The Solution Of the Problem 3

• The Lathe Machine amend quickly , first lathe machine create to slash wood object . And now lathe machine can slash hard object quickly .
• Lathe Machine can slash iron object easily, so we can shaping that to other form without difficulty .

4.3 Disscussions

In our opinion , The lathe Machine made to facilitate humans slashing or shaping emetal object easily and quickly .

CHAPTER V

CONCLUSSION AND SUGGESTIONS

5.1 Conclusion

History began when humans first construct a rigid frame pads to support the work piece can be played on a coil and cut into a circular shape with a handheld device. Mendelsches Bruderbuch 1395, shows a frame lathe and sledge made ​​of heavy wood to increase rigidity.   Difficulty holding the cutting tool firmly when cutting hard materials discovery spawned major sled where the wheels have a tremendous advantage because it produces a constant speed and thus increase the control over the cutting tools.

In 1797, Henry Mauldslay (1771-1831) designed and built a machine called a lathe screw cutting lathe, s ne of the work developed in the state of New England.

5.2 Suggestions

Berdasarkan kesimpulan tersebut, makalah ini mempunyai banyak kekurangan dan jauhnya dari kesempurnaan, oleh karena itu segala kritik dan saran yang bersifat membangun sangat lah penulis harapkan terutama dari bapak guru pembimbing dan rekan pembaca sekalian demi kesempurnaan makalah ini dimasa mendatang, semoga makalah ini bermanfaat untuk kita semua dan menambah wawasan kita.
