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.
