Dynamic Acceptance Tests for Machine Tools 271 reasons, they could be used, in certain cases, as the first approximation of a measure of their dynamic performance. Consider again Fig. 2. It will be remembered that Fig. 2(b) is derived from Fig. 2(a) by increasing by 25 per cent the stiffness of the mode which tended to become unstable.
Know the difference between a Factory and Site Acceptance Test. One of the biggest areas of confusion surrounding the FAT is over whether it should simulate how the machine responds under actual factory conditions. In fact, that is the purpose of the Site Acceptance Test (SAT).
fully passed the acceptance tests at the customer''s site. The commissioning was completed . with an acceptance test: remilling the notches in the table. Two 12 m long machine beds had to be milled so precisely that they fit together perfectly once they were bolted together without having to be recut. The ProfiMill fulfilled this
Session 11 Standards for Machinery Acceptance Testing and Balancing 1. Introduction. An important question we have not yet considered is „What is an acceptable level of vibration for the machines that are under our care?‟ Since the 1960‟s there have been numerous Standards published internationally dealing directly or
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavyduty gang milling operations.
