Description

4473/CYMRU/RH/25 Drilling Spindle Integration

The University of Sheffield Research Centre (AMRC Cymru, located in Broughton, Flintshire) is in the process of creating an aerospace drilling and fastening centre to carry out projects and development activities centred around drilling and fastening capabilities.

The first stage of this project required the creation of a drilling machine. The current features of this machine are:

• a small drilling spindle,

• a rotational horizontal axis allowing the workpiece and spindle to rotate together from 0 to 180 degrees,

• an MQL system,

• an industrial vacuum for extraction during the drilling process

• a sensorised fixture and data acquisition system

• Beckhoff PLC controller connected to the drilling machine and MQL system.

• Power distribution board and air outlets

AMRC Cymru would like a knowledgeable supplier to complete the integration of an upgraded spindle (selected and purchased by AMRC Cymru), into the existing drilling machine. Additionally, a number of cell upgrades will be required. The supplier will be

required to work closely with the AMRC and the chosen spindle supplier to ensure smooth integration, testing and commissioning.

To fulfil this tender, the following tasks are required:

• Integrating the new drilling spindle into the existing drilling jig, making the necessary modifications (e.g. creating mounting holes on the carriages).

• Designing, manufacturing and integration of movable X/Y axes to the existing drilling machine to allow movement of the sensorised fixture (Figure 2 below) to allow multiple holes to be drilled in one workpiece (coupon).

• Integrating the Fusion Systems Pure-Cut®+ scCO2 system into the drilling spindle and cell and associated tooling to enable this such as scCO2 compatible tool holders.

• Updating the Beckhoff control system to run the new drilling spindle via the HMI, including speeds, feeds and setting up the vibrational frequency and amplitude requirements.

The spindle supplied will have the MS1215 Drive that will need to be integrated with the Beckhoff Control system.

• Updating the Beckhoff control system to allow movement on the X/Y axis via the HMI.

• Carrying out tests and commissioning work to ensure that all systems are working together and are able to carry out differing drilling parameters for tests (to be agreed at a

later date with selected supplier).

• Updating the current UKCA marking to include the modifications that will be carried out that includes the new drilling spindle and the X/Y table.

• Full design review for acceptance of the proposal using a Preliminary Design Review, Critical Design Review and Final Design Review gate system.
