78 16 Installation and Adjustment Guidelines for MINIRAIL and MINISCALE PLUS 16.2 Installation Methods Different criteria must be taken into consideration when choosing an appropriate installation method and defining the number and arrangement of the lateral reference surfaces. These are: 16.2.1 Load 16.2.2 Accuracy 16.2.3 Installation time and engineering expense 16.2.4 Installation location and specifics 16.2.1 Load Forces in the direction of tension/compression do not have any influence on the lateral reference surfaces. If side loads emerge which exceed the permitted lateral force, references and lateral clamping must be specified. Number and orientation depend on the forces that occur. The reference surfaces should be arranged based on the direction of force of the main load. Lateral references should also be provided when vibration and impacts occur. They also increase the rigidity of the system. 16.2.2 Accuracy Lateral reference surfaces are recommended if a high level of guideway accuracy is required. The references make installation easier and reduce the complexity involved in ensuring accuracy. The guideway accuracy is determined by the straightness of the reference surfaces and by the guide rail compression process and/or by the accuracy of the lateral clamping. 16.2.3 Installation Time and Engineering Expense Reference surfaces make installation easier and reduce the complexity involved in aligning the guide rails. With careful manual alignment of the guideway, it is possible to dispense with the need for lateral reference surfaces. When deciding on a method, the complexity of the installation should be carefully considered and compared with the design and technical manufacturing complexity. 16.2.4 Installation Location and Specifics Reference surfaces and lateral clamping require additional installation space and access to the installation areas. It is therefore important to check whether the provided references and adjustments are compatible with the installation area in the machine. Shown below are some typical installation methods which differ in terms of the number and orientation of the reference surfaces, the transferable lateral forces and the complexity of installation, and are intended to serve as a design aid.
