Objective
The achievements to date are the specification of current saw manufacturing practices on saw blade vibrational behaviour. The manufacturing steps heat treatment, milling of the teeth, straightening and pretensioning, thickness grinding, diameter grinding and final straightening have been investigated in relation to vibration patterns, decay behaviour after excitation, natural frequencies and flexural rigidity. An improved diamond segment and sawblade design was developed and the cutting conditions established. The characteristics and composition of the raw material (marbles) are described.
The technological advantage of the result is that cutting performance has improved. During the cutting process, the new type of saw blade produces less noise and less waste than current types of saw blade.
The economic benefits obtained are a reduction of tool downtime, improved surface quality, narrower kerf and material saving.
A calculation model allows cutting conditions to be chosen in relation to high productivity or lowest costs per sawn area. The new sawblades produce 16% less dust and create a sound pressure level which is 9 dB(A) lower than that of standard sawblades.
Applications include the cutting of stone, marble, granite, etc and possibly plastics, ceramics and concrete plates.
When using disklike diamonds saws, the main characteristic with significant influence on the cutting process and the quality of the workpieces is their vibration behaviour. This vibration is influenced by the dimensions of the saw blade, the state of residual stresses and the construction of the saw body and must be adapted to the machine and the cutting process. The main objective of this project is the adaption, transfer and application of innovative saw design practices in order to eliminate stepwise cutting with different diameter saws to achieve deep cuts and instead the use of saws with improved abilities. Economic benefits will be obtained through reduction of tool downtime, improved surface quality, narrower kerf and better use of the raw material.
