Sawing of timber

Sawing of timber is a timber that is cut from logs into different shapes and sizes. Sawing of timber is generally cut into varying rectangular widths and lengths, but may also be wedge-shaped. Common  Sawing of timber products include solid timber beams and more rectangular timber sections.

• The process of giving the required shape and size to the timber section is termed as conversion sawing of timber.
• By sawing, timber can be converted into transferable parts.
• Various methods of Sawing of timber are…

i. ORDINARY/ FLAT/ SLAB SAWING:-

• parallel cuts made throughout the length of the log i.e. tangential to the annual rings.
• Easiest and economical method.
• Causing twisting and warping of planks.

• 

ii. QUARTER SAWING:-

• When applied to wood not having distinct medullary rays, this method produces very fine wood.
• In this method saw cuts are made at right angles to each other.
• The tendency to cup i.e. to curve in a transverse direction.

iii. TANGENTIAL SAWING:-

• In this saw, cuts are made tangential to annual rings that meet each other at right angles.
• It is suitable for those sections which have distinct annual rings and indistinct medullary rays.
• Not suitable for flooring.
• The section observed to have the least strength.

iv. RADIAL/ RIFT SAWING OF TIMBER:-

• Saw cuts are in a radial direction parallel to medullary rays in this method.
• Wastage of timber is observed to have maximum in this method.
• Section obtained is having maximum strength and induces decorative effect too.
