Problem

There are a group of issues that regularly occur with the SR axis on the Autoflow. The proposed upgrades solve all of them with a package of measures

The issues are:

SR Axis Issues
No	Issue	Solution
1	The SR axis datum sensor in its designed position on a Mk4 is prone to breakage with offcuts. On Mk4 machine, the orientation on an arc makes setup unreliable and difficult	Move the SR datum sensor to a point higher on the assembly, away from the swarf and change its orientation so it works from a flat plate rather than an arc.
2	Moving the SR sensor creates another issue with reliability as offcuts at the top can be thrown into this area, breaking the sensor holder and the sensor	Design a deflector plate to improve offcut management in this area
3	The SR axis slewing ring seal can be pulled out with a sharp offcut as area acts like a "bucket" for swarf and offcuts	Design a cover system to enclose the base area
4	The later SR axis slewing rings have a greasing point on the inside of the ring that can be wiped out by the same offcuts	Cover system needs to protect the greasing points, and they need to be piped and routed so that the greasing points are more accessible
5	The end stop on the SR axis is poorly designed and unreliable on the Mk4 design	Design a system that can be retrofitted, given the change in design of the steel framework
