Module Name: Advanced Manufacturing Engineering and Management Practice

Module No: PDE 4221

Coursework Mark: 35%

Submission deadline: Friday 8 January 2010

Problem:

Affordable Automation Ltd, based in Manchester, has been commissioned to supply an electro-mechanical

handling system. The machine is to have two axes, X and Z, and will be used to carry sink tap units in

preparation for painting or plating. Z-axis will be mounted on a fixed beam section travelling along the X-

Axis, and will have a suitable area for loading a batch of 10 taps. The overall mass of the Z-axis is estimatedto be 28 kg. The taps are made from brass and will be required to be cleaned and dried prior to being plated.

The monoblock sink mixer taps are to be supplied to Ideal Standard Limited for their Tantadisc range (P/N

E6816AA), catalogue number 9:4:6. The estimated gross mass of the unassembled taps is 2.5 kg (body and

spout). The lever handles of the taps will be cleaned using another carrier and is not part of this task. The frame is to be built by another company, Machine Building Systems (MBS) based in Derby, using

aluminium alloy extrusions manufactured by a German company, Item. A proposed configuration of thesystem is provided by MBS with some overall dimensional details in Figure 1.

The vertical axis is a telescopic construction and offers an effective area of 300 mm x 300 mm to mount a

suitable tap carrier (body and spout). The company would like to have the taps pre-loaded onto these carriers

and then loaded onto the gantry. The depth of each station is 0.9 m (cleaning, rinsing and drying). Once

carrier is loaded, there should be no free movement other than the natural flexing of the structure.

It is worth noting that each end of the cross slide beam will be mounted onto a pair of linear bearing blocks.Z-axis is to be mounted at midpoint along the cross slide.

Task:

1-  Specify a suitable section for the Z-Axis and its associated components using the Item catalogue. You can

obtain an electronic version of their catalogue at www mbsitem co uk and www item
