Its 280 mm long. and cross section at end needs to be reduced.
280 long? In mm that's awful short? In cm that's pretty long , in " you gotta be kidding?

Thank you Sir; it is of 13 mm diameter OD which has to be necked down to 10 mm. i have tried using screw press and necking die, using mandrel but the component is cracking at one end or in some cases just buckling,twisting.
13mm? 13 Inches?
The general way in production is to use a swaging machine with dies shaped to the OD you wish to achieve. It can be done cold, warm or hot.
In general one must support the tube while the reduction occurs or it will buckle/fold so just hitting it with a hammer is not a good way to go.
I suggest a search for tube swaging on youtube.

What is the best method to make an aluminium tube of 13 OD,280 length and having a reduced cross section at one end? One 'piece' of the foldable cane used by blind people for example

I have done a process where the cutting tool is just below the tube and fed in longtitudina direction. The tube diameter is progressivey getting reduced.
