Primary, secondary and tertiary industries for steel products

Realitas Manufaktur Modern • Globalisasi - Setelah negara-negara terbelakang (misalnya, Cina, India, Mexico) menjadi pemain utama dibidang manufaktur. • Internasional outsourcing - Bagian dan produk yang telah dibuat di Amerika Serikat oleh perusahaan-perusahaan Amerika sekarang dibuat di luar negeri atau negara tetangga (di Meksiko dan Amerika Tengah). • Lokal outsourcing - Penggunaan pemasok di AS untuk menyediakan suku cadang dan servis.

Realitas Manufaktur Modern • Kontrak manufaktur - Perusahaan yang mengkhususkan diri di bidang manufaktur produk keseluruhan, bukan hanya komponen, dikontrak oleh perusahaan lain. • Trend - terhadap sektor jasa dalam ekonomi AS. • Kualitas - harapan - Pelanggan, baik konsumen dan korporasi, menginginkan produk dengan kualitas terbaik. • Perlu untuk efisiensi operasional - produsen di A.S harus efisien dalam dalam operasi mereka untuk mengatasi keunggulan biaya tenaga kerja pesaing internasional

Pendekatan dan Teknologi Manufaktur Modern • Otomasi - peralatan otomatis bukan tenaga kerja • Teknologi material handling - karena manufaktur biasanya melibatkan suatu urutan kegiatan • Sistem Manufaktur - integrasi dan koordinasi beberapa workstation otomatis atau manual • Manufaktur Fleksibel - untuk bersaing dalam kategori produk volume-rendah/sangat beragam • Program kualitas - untuk mencapai kualitas tinggi yang diharapkan oleh pelanggan saat ini • CIM - untuk mengintegrasikan desain, produksi, dan logistik • Produksi dengan hemat/ramping - bekerja lebih dengan sumber daya yang lebih sedikit

Definisi CAD/CAM/CAE Definisi CAD Computer Aided Design (CAD) is the technology concerned with the use of computer systems to assist in the creation, modification, analysis, and optimization of a design [Groover & Zimmers 1991]

Definisi CAD/CAM/CAE Definisi CAM Computer Aided Manufacturing (CAM) is the technology concerned with the use of computer systems to plan, manage, and control manufacturing operations throught either direct or indirect computer interface with the plant’s production resources. [Groover & Zimmers 1991]

Definisi CAD/CAM/CAE Definisi CAE; Computer Aided Engineering (CAE) is the technology concerned with the use of computer systems to analyze CAD geometry, allowing the designer to simulate and study how the product will behave so that the design can be refined and optimized. [Groover & Zimmers 1991]

CAD Computer Assisted Drawing Using a computer to make vectorbased drawings.

CAM Computer Assisted Machining

Using a computer controlled machine to produce actual parts from a CAD drawing.

4 steps in any CAD/CAM operation:

1. 2. 3. 4.

Geometry Creation Toolpath Creation Post Processing Machining the Final Part

1. Geometry Creation Producing a vector-based drawing of the part you want to make.

3 Ways to Create Geometry • •

•

Draw it in CAD Convert a raster-based drawing to vectors 3D scan of an existing object

1. Geometry Creation - Using CAD CAD programs make vector-based (mathematically calculated) entities. Some common CAD formats include: •

Mastercam - .mc9 • AutoCAD - .dwg • Microstation - .dgn • Drawing Exchange Format - .dxf

1. Geometry Creation - Raster to Vector conversion Most graphics programs make raster-based (dots on screen) images that must be changed to vectors so they can be used for CAM. Some common raster formats include: •

Raster

Vector

MS Paint - .bmp • Internet images - .jpg • Graphics editors - .gif • Scanned images - .tif

1. Geometry Creation - 3D Scan The scanner measures millions of points on an object and records them as co-ordinates which are then used to create the vector geometry.

Laser scanner…

turns this object…

into this geometry.

2. Toolpath Creation Using the geometry to make a “road map” that the cutting tool will follow in order to machine the part. Several parameters must be set:

• Type of tool used • Cutting speeds, depths, and feed rates • Material to be cut • Rough and finish settings

2. Toolpath Creation - Verification Most software will let you see a simulation of your part being cut so you can verify that the toolpath information is correct.

3. Post Processing Translating the toolpath information into a programming language called G-Code that controls the machine.

From toolpath… …to G-Code.

4. Machining the Final Part The machine reads the G-Code and follows the toolpath to cut the part.

From CAM definition, the application of CAM falls into two broad categories: 1. Computer monitoring and control .

Integrasi CAD/CAM/CAE to CIM

CIM 

Computer-integrated manufacturing (CIM) is the use of computer techniques to integrate manufacturing activities. These activities encompass all functions necessary to translate customer needs into a final product. CIM starts with the development of a product concept that may exist in the marketing organization; includes product design and specification, usually the responsibility of an engineering organization; and extends through production into delivery and after-sales activities that reside in a field service or sales organization. Integration of these activities requires that accurate information be available when needed and in the format required by the person or group requesting the data. Data may come directly from the originating source or through an intermediate database according to Jorgensen and Krause. CIM systems have emerged as a result of the developments in manufacturing and computer technology.

Part and product design. There are four phases that are crucial in part and product design. They include preliminary design, refinement, analysis, and implementation. Tool and fixture design. Tooling engineers using computer-aided design (CAD) tools to develop the systems or fixtures that produce the parts. Process planning. The process planner designs a plan that outlines the routes, operations, machines, and tools required. He or she also attempts to minimize cost, manufacturing time, and machine idle time while maximizing productivity and quality. Programming of numerically controlled machines and material handling systems. Production planning. There are two concepts used here including materials requirement planning (MRP) and machine loading and scheduling. Machining. This is part of the actual manufacturing process, including turning, drilling, and face milling for metal removal operations. Assembly. After they are manufactured, parts and subassemblies are put together with other parts to create a finished product or subassembly. Maintenance. Computers can monitor, intervene, and even correct machine malfunctions as well as quality issues within manufacturing. Quality control. This involves three steps including system design, parameter design, and tolerance design. Inspection. This stage determines if there have been errors and quality issues during the manufacturing of the product. Storage and retrieval. These tasks involve raw materials, work-in-process inventory, finished goods, and equipment.

Sistem Manufaktur Otomatis Contoh:  Mesin perkakas otomatis  Jalur transfer  Sistem perakitan otomatis  Robot industri yang melakukan operasi pengolahan atau perakitan  Material handling dan sistem penyimpanan otomatis untuk mengintegrasikan operasi manufaktur  Sistem pemeriksaan otomatis untuk pengendalian kualitas

Otomatisasi dalam Sistem Produksi Dua kategori otomatisasi dalam sistem produksi:  1. Otomatisasi sistem manufaktur di pabrik  2. Komputerisasi sistem pendukung manufaktur

Dua kategori akan saling melengkapi karena sistem  pendukung manufaktur terhubungkan ke sistem  pabrik manufaktur

Sistem Manufaktur Otomatis 

  

Tiga jenis dasar: 1. Otomatisasi tetap 2. Otomasi yang dapat diprogram 3. Otomatisasi yang fleksibel

Otomatisasi Tetap Sebuah sistem produksi di mana urutan operasi proses (atau perakitan) ditetapkan oleh konfigurasi peralatan Fitur khas:  Cocok untuk jumlah produksi yang tinggi  Investasi awal yang tinggi untuk peralatan yang dirancang khusus  Tingkat produksi tinggi  Relatif tidak fleksibel dalam mengakomodasi perubahan produk

Otomasi yang Dapat Diprogram Sebuah sistem manufaktur yang dirancang dengan kemampuan untuk mengubah urutan operasi untuk mengakomodasi konfigurasi produk yang berbeda Fitur-fitur khas:  Investasi tinggi pada peralatan yang memiliki banyak kemampuan (general purpose)  Tingkat produksi lebih rendah daripada otomasi tetap  Fleksibilitas untuk menangani variasi dan perubahan dalam konfigurasi produk  Paling cocok untuk produksi batch  Setup fisik dan program untuk komponen harus diubah antara pekerjaan (batch) 

Otomasi Yang fleksibel 

Perpanjangan otomasi yang dapat diprogram di mana sistem mampu beralih dari satu pekerjaan ke pekerjaan berikutnya tanpa waktu yang hilang antara pekerjaan

Fitur-fitur khas:  Investasi tinggi untuk sistem yang secara teknis dirancang khusus  Produksi secara kontinyu produk campuran yang dapat berubah  Tingkat produksi menengah  Fleksibilitas untuk menangani variasi produk yang tidak mencolok

Sistem Pendukung Manufaktur dengan Komputer Tujuan otomatisasi sistem pendukung manufaktur:  Untuk mengurangi jumlah upaya manual dan administrasi dalam desain produk, perencanaan produksi dan kontrol, dan fungsi-fungsi bisnis  Mengintegrasikan desain berbantuan komputer (CAD) dan manufaktur berbantuan komputer (CAM) dalam CAD / CAM  CIM mencakup CAD / CAM dan fungsi bisnis perusahaan
