FACTORY ACCEPTANCE TESTING LEVEL 1 FAT Overview A Level 1 FAT is the most basic level of equipment/system testing conducted at the OEM. This is often the level of acceptance test for equipment that is similar to other equipment in the plant or for equipment that has simple to moderate upgrades and/or modifications.
Some of them serve for determining the conditions under which a machine tool can be used without the danger of chatter, others serve for the testing and improving of newly designed and prototype machines. As far as acceptance tests for standard machines rather than prototypes are concerned, finishing cuts be still taken for determining the ...
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.
At NC SERVICE our retrofitting process goes beyond the mere mechanical restoration of our customers'' milling machines, to include either the retrofitting or upgrading of the machine''s electrics, electronics or numerical control. This part of the milling machine is generally the first to become obsolete.
In this test dial indicator is mounted on one of the surfaces whose alignment is to be tested with another surface. In case of a horizontal milling machine the testing of the alignment between the spindle and the over arm support can be done as shown in fig. 44 Machine Tool Alignment Tests
Session 11 Standards for Machinery Acceptance Testing and Balancing 1. Introduction.

Making a Great Factory Acceptance Test. What makes for a successful factory acceptance test is plenty of test materials that are what will be used in the plant, skilled people who want to learn, and realistic expectations for what a factor acceptance test can provide.
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.
