1 Basic
information
1.1 Prerequisites
1.1.1 Target
group
The standard application is conceived for all programmers and users who
wish to quickly and simply implement a flying saw using SIMOTION.
1.1.2 Knowledge
base
In order to use this technology template, you should be able to use SCOUT
and technology objects and technology function calls in SIMOTION.
This document does not provide an introduction into these subjects and is
solely restricted to providing information and data on how to use this
standard application.
1.1.3 Technical
environment
This standard application can only be used, without having to make any
changes, in conjunction with SIMOTION D and the SINAMICS
demonstration case.
1.2
Objective and purpose of this standard application
1.2.1 Task
description
Using SIMOTION, a material web, fed using the material feed mechanism
is to be cut into identical parts and sections. As a result of the
characteristics of the material, the material cannot be cut at once across
the whole width of the web with just one cut. In order that the motion of the
material web does not have an impact on the cut, either the material web
must be stopped during the cut, or the cutting device must be moved in
synchronism with the material web – i.e. the material web is cut "on the fly".
Why flying processing/machining?
"Flying" processing/machining is required, if
• If the flow of products were to be stopped due to a sub-process
(generally a thermal process) this would result in a reduction in quality
or even waste.
• Stopping the product flow cannot be justified as a result of the energy
demand when decelerating and accelerating.
• The individual processing/machining steps are too different so that a
standard delay time cannot be justified from a cost-effective
perspective.
