Auditing Wood Machining Processes Used For Making Furniture

We work more and more furniture related projects, so we thought that creating a specific checklist for these processes was necessary.


 
The difficulty encountered was the many types of wooden furniture. We were forced to make certain assumptions in order to limit the scope and make physical audit manageable:

  •     All wooden furniture starts as raw material
  •     All wood furniture has some kind of shaping process in order to get the wood that looks like the end product
  •     All wood furniture has some type of finish applied to the wood
  •     All wood furniture ends as a finished product, either a fully assembled piece or as a product in a kit form where the consumer meets the product when they get home

So, given these assumptions, we look at the process of making wooden furniture in more detail.

We cover topics such as wood moisture and drying processes and how we are controlled. It is very important to understand the moisture content of wood, particularly when changes in the moisture content may change the dimensions of the timber, which could cause serious defects in the final product.

Turning a piece of wood in a wooden cabinet requires a number of different steps: cutting, sanding, shaping, laminating, gluing, drilling, painting and / or varnishing, screws, staples, printing (logos or names), assembly and some cases as a sofa or chair that is like adding furniture covers foam and fabric.

We have reviewed these process steps, broken down into sections where we examine the operational elements to assess the risks to the client. It is at this level where we look at the attention to detail, the way the process is repeatable, the use of jigs and fixtures, and how safe working conditions are, for example.

The objective of this type of audit process is to allow the client to determine the risks associated with a particular manufacturer, and to make a list of high-priority improvements.

Sections covered in this audit are:
  •     Welcome Timber
  •     Drying of Wood
  •     The wood cut to size - Shaping
  •     Drilling
  •     Sand
  •     Glued
  •     Painting / Spraying
  •     Polishing / Coating
  •     Assembly screw
  •     Serigraphy
  •     Pad Printing
  •     Health and Safety
  •     In Process Quality Control (IPQC)
  •     Work in Progress (WIP)
  •     Mount Upholstery
  •     Packaging
