0)en t&e 'inal selected $ro,ect needs to (e com$leted in a timely 'as&ion as t&is $roduct is due tomo)e Kune 2"1"- and I am concerned t&at t&is time scale could (e (roug&t 'or*ard.
Also *it& t&ese $ro,ects (eing (ased in a $roduction en)ironment t&e sti$ulation o' &a)ing a nonim$act on $roduction +uantities &as (een im$osed on any *or/ I carry out on t&is $ro,ect.
T&is did &a)e an in'luence on t&e 'inal selection as t&ere is a second o)en t&at I can use to doany trials on- t&at is only utilised (y $roduction 5" o' t&e time.
T&ere are ot&er met&ods a)aila(le to ac&ie)e t&e t&ermal e$ansion re+uired *it&out using an
o)en? t&ese usually in)ol)e a$$lying &eated coils to local areas on a com$onent. T&e costrestrains on t&is $ro,ect immediately made t&e $urc&ase o' t&is ty$e o' e+ui$ment unD'easi(le.
It s&ould (e $ossi(le to calculate t&e e$ansions re+uired as t&e materials and tem$eratures are/no*n. T&is s&ould (e straig&t 'or*ard on t&e initial assem(ly (ut on t&e disassem(ly met&od t&eadded com$leity o' &a)ing t&e (ot& stator and t&e motor *inding t&ermal coe''icients tocalculate.
or t&is reason t&e 'inal design *ill (e e)aluated on collected em$irical data.
%aterial inear coe''icient NC Bolumetric coe''icient- β- at 2" NC Aluminium 23 6!Steel 11D13 33D3!
or t&e tooling design I *ill use current t&ree dimensional design tools and create a 3# model o't&e 'inal design (e'ore manu'acturing t&e tool. T&is &as so many (ene'its o)er using 2# dra*ingsas t&e tool *ill )isually a$$ear to &a)e de$t& and e)en teture on a com$uter screen.
nce t&e tool is com$lete I *ill (e a(le to de'ine a minimum tem$erature t&at t&is o$eration can(e carried out at. T&e reason 'or t&is is t&at t&e 'eed *ires to t&e motor *inding are s&ea)ed in*&at is t&oug&t to (e PBC. T&is $ro,ect *ill de'ine t&e actual material and i' t&e remo)altem$erature can (e set (elo* t&e PBC =or de'ined material> melt $oint t&en t&e *indings can (ereDused a'ter disassem(ly as *ell.

Lsing %icroso't $ro,ect to $lan t&e $ro,ect made t&e tas/ )ery easy- and also &as t&e a(ility to$roduce CP% c&arts i' re+uired. T&e dates used are not 'ied (ut estimated so I e$ect t&isdocument to &a)e c&anged (e'ore t&e 'inal $ro,ect is com$leted. It also &as t&e a(ility to allocateresources to $articular elements o' t&e $ro,ect (ut as I am t&e main resource 'or t&is $ro,ect t&ent&is 'unction is not re+uired.
