Creating patterns where grain must match for groups of parts
For some parts with grained material it is important that the grain on each part matches in the final product. These parts therefore need to be produced from the same area of the board so that the grain or finish matches. Common examples of this are drawer fronts or pairs of cabinet doors.
To achieve grain matching a set of pattern templates are set up in the Pattern library. These templates specify how the various groups of parts (e.g. drawer fronts or doors) are to be arranged. Use these templates when entering parts (in a part list or part library) to specify how the part is arranged.
Where parts are specified for grain matching the optimisers automatically always place the parts in cutting patterns in the specified fixed arrangement.
Setup
- The predefined Information box: Grain matching must be included in the part list fields so that the part arrangement can be set for each part.
- Use the Pattern properties for the template to specify how the grain matching operates, for example, whether to cut the parts in the pattern or produce a jumbo or master pattern for the group of parts - which is divided later.
- At the part list set the optimising parameter and saw parameter files to use before the cutting list is created. This ensures the correct saw blade thickness and saw trim values are used for the calculation of the cutting size and not the values set in the template. (If parameter files are NOT set at the part list the values in the template are used).
