What is lath machine and it's working principale

Working Principale:- 

                 The lath machine remains undesirable materials from a roasting work in the from of chips. This is done with the help of a tools which is traversed across the work pice and can be fed deep into the work pice.
                   Lath machine holds the work  pice between the two right and strong support called center or in a chuck or face plate in mounted on projected end of the machine spindal.
   The cutting tool is rigidly hold and supported in a tool post and is fed against  the revolving work pice. The tool is made to move eighter paralal to or at an ivolnetion while,the work pice revolves about its own axis.It is fed paralal to the axis a cylindrical surface is obtained. To obtained a traped surface it should be fed inclined a cirten angale.

TYPES OF LATH:---
          (1) Banch Lath -- This lath machine is small in size it is similar to the center lath .It is used to produce simple  small and accrute job.

          (2)Speed Lath  -- It is the simpleset of all the lath machine and it's designed to be operated menualy . It is used for wood working and polishing work.

          (3)Turrate Lath --This lath mechine is considered appropiate for nlarge scale peoduction. This make it possible multiple tools attchments to be attached.

          (4)Tool Room Lath--It is an accruate mechine of highe hpeed range and it similar to the Center Lath mechine.

          (5) Automatic lath--Automatic lath machine usually developed for mass production automatically. fed in raw materials changing tools and fed veering speed and removing the job can be performed automatically.

          (6)T Lath --This type of lath is used for the motor of Jet engine.The shape of the lath look like a english alphabet 'T' that's why it's called T lath.

          (7)Capstan Lath--Capstan Lath is alight duty machine

          (8)Special Purpose Lath--It is multi production machine and it's deigned only for specific operation         
          (9)Engine Lath-- This type of lath machine is commonly devloyd in industries and it used to perform operation such as turning , facing , drilling , boring , thared cutting , etc. It's headstock is bigger in size and robust.

SPECIFICATION OF LATH--
        *The height of the centers measured from the lath bed.
        *Swing diameter over the bed.
        *Swing diameter over the carriage.
        *Maximum bar diameter- this is the maximum diameter that will paas through hadestock spindle.
        *Length of the bed.
