Automated gantry loading of modular block tooling from magazine to a turning centre s turret. Courtesy of Sandvik Coromant the machine tool - more will be said on this subject later in the chapter. These tooling aids also minimise the setter operator activity and this will ensure that such vital information is correctly performed thereby eliminating the risk of mistakes being made during any hectic machine stoppages. While another benefit of using a quick-change modular tooling strategy is that the time needed to change tools is very short. It may even be possible to make an unscheduled tool change for critical tooling if for example their wearrate is unexpectedly high. This unscheduled tooling adjustment will raise the overall cutting performance which in turn leads to improved and economical tool utilisation particularly during a large production run. Where a company is involved in large-batch or massproduction runs its should be obvious by now that utilising modular quick-change tooling offers considerable savings by reducing the non-productive cutting times. This modular tooling strategy is also true but to a lesser degree for either small batches and can even be relevant in the extreme case for certain one-offs requiring many tool changes in the machining of a complex part geometry. This latter factor is particularly the case when part families 4 are required to be produced. Frequently the problem that is present within a machine shop is one of insufficient tool storage on the actual machine tool this is particularly the case for single-turret turning centres - having limited pockets available for the tooling. Under such circumstances the solution may be to use modular quick-change tooling. Using say minimal levels of tooling automation via semi-automatic quick-change tooling extends the turret s capacity with minimal loss of productive cutting. Replacing a new cutting club head simply requires the operator to lift out the old unit .
