Flexibility ?

The ability to deal with slightly or greatly mixed parts,

To allow variation in parts assembly and variations in process sequence, change the production volume and change the design of certain product being manufacturing.

slide3

Another statement about flexibility….

  • Flexibility become a key consideration in the design of manufacturing system.
  • Support changes in production capabilities or activities.
  • The ability of a system to cope with changing circumstances (situation).
  • Consists of various different components such as machine flexibility, routing flexibility, volume flexibility etc
slide4

Definition of Flexible Manufacturing System

“Consists of a group of processing stations (usually CNC machines) ; interconnected by means of an automated handling and storage system and controlled by an integrated computer system.”

Capable of processing a variety of different types of job/part under NC program control at the various workstations so we can refer it as FMS

slide5

Flexibility is generally considered to 2 categories, which is :

a) Machine flexibility

The ability to be changed to produce new product types, and ability to change the order of operations executed on a part.

b) Routing flexibility

The ability to use multiple machines to perform the

same operation on a part, as well as the system's

ability to absorb large-scale changes, such as in

volume, capacity, or capability.

slide6

Components of FMS

Processing Stations

CNC machine tools to perform machine operations on families part.

Material Handling Devices

Used to transport the work parts and subassemblies between the processing stations.

Used for loading and unloading raw materials and finished parts.

Auxiliary Equipments (Peralatantambahan)

FMS can include cleaning, automated measurement and inspection equipment.

Computer Control System

To co-ordinate the activities of the processing stations and material handling system.

FMS Applications

Example : Vought Aerospace FMS

Installation plan of the Vought workshop F.M.S

slide9

Elements of the Vought F.M.S.: -

  • Eight 4-axes Milacron 20 HC horizontal machining centre with Allen Bradley numerical control and a 90 capacity tool magazine.
  • A washing station.
  • 4 wire-guided vehicles.
  • Two Carousals, each with 10 spaces.
  • Two D.E.A. vertical measuring machines, with transverse movement and heads with two axes of rotation.
  • A rectification centre.
  • Swarf treating system.
slide11

FMS Flanging machine is a totally hydraulic machine suitable for the flanging of bottoms of different thickness with or without central hole.

The machine is made up of a bottom holding trolley with vertical and horizontal movements, a forming roll on which the roll is presses to get the desired radius, a flanging roll which is used to adapt the bottom to the forming roll, guiding rolls which move on suitable guides which have the function to keep the bottom pressed against the forming roll.

slide12

BAMTRI has offered a large number of advanced manufacturing technologies and equipments for the development of new type aircraft, aero engines, and technical renovations to aircraft manufacturers.

CAD Definition :

An approach to product and process design that

utilizes the power of computer. It involves the

computer to create design drawings and product

models.

Lagi tentang CAD…

  • Jenis-jenis komputer di dalam industri :
  • Komputer untuk merekabentuk produk
  • Komputer untuk mengawal robot
  • Komputer untuk merekod inventori
  • Komputer untuk menganalisa perancangan industri
  • Komputer untuk mengendalikan kewangan industri
  • Antara sistem yg digunakan dalam industri pembuatan adalah CAD
  • Antara kelebihan CAD :
  • a) Rekabentuk grafik lebih tepat dan jitu serta lengkap dengan senarai
  • bahan serta spesifikasi seperti ukuran, ketahanan dsb.
  • b) Mempercepatkan lg proses merekabentuk
  • Contoh perisian yang popular : AutoCAD; APT-X, NPU-CAD/CAM,
  • Panda Systems; ECADS, AEDS, CATIA dan terkini SolidWorks
slide17

Sejarah CAD

  • Muncul dr tahun 1964 dan mula digunakan
  • sepenuhnya pd tahun 1982
  • Peringkat awal program CAD ditulis dlm
  • bahasa pengaturcaraanFOTRAN
  • (FORmula TRANslator) dan juga PASCAL.

Peringkat-peringkat Rekabentuk

  • Menetapkan apakah rekabentuk yg ingin dicapai
  • Memikirkan cara-cara untuk memulakan melukis rekaan
  • Segala maklumat yg dikumpul untuk rekaan mestilah direkodkan dan
  • Didokumentasikan untuk tujuan perkilangan
  • 1.Konsep 2.Sintesis 3.Analisis
  • 4.Ukuran perbandingan (Evaluation) 5.Dokumentasi
  • Model Peringkat Rekabentuk berasaskan 3F :
  • Form : Faktor rupa, gaya dan bentuk rekaan
  • Fit : Keupayaan kpd permintaan pasaran atau keselamatan ; pengguna
  • Satisfy atau tidak? Atau selamat ?
  • Function : Fungsi rekaan (Cth skru)
