Yang bisa dilakukan dalam CAM :
◦ CAPP (Computer Aided Process Planing =
persiapan pekerjaan yang dibantu dengan
komputer)
p
)
◦ Pemrograman NC (Numerical Control) dan
pemrograman robot
◦ Pembuatan instruksi pekerjaan (peraturan kerja)
◦ Perencanaan material dan penyediaan perkakas
potong dan alat-alat penjepit
◦ Dasar FMS (sistem komputer untuk pengontrolan
sistem produksi yang fleksibel)

proses produksi berdasarkan geometri
dari part yang akan dibuat
dibuat, jumlah

CAPP mampu memilih tool dan fixture
terbaik serta menghitung biaya dan

Mengapa CIM perlu
Customer memiliki keinginan
g
dan
tingkat kepuasan yang berbeda-beda
y Permintaan akan produk sangat
variatif dan fluktuatif
y Dibutuhkan sistem produksi yang
mengintegrasi teknologi baru agar
mampu merespon cepat terhadap
permintaan customer.

Function of CIM
1) Order information and automatic
scheduling through computer
- dealing individual orders of various
products
- control of due dates
- preparing production planning
2) Inventory control through JIT
- minimizing raw material, WIP,
inventory
- utilizing bar code, RFID
3)) Statistical q

6) Managing MIS Data
- reducing indirect cost
- rapid decision making using
database
7) Diagnosing failure

- minimizing
- details of failure (problems)
8) Managing Technical Data, Document
- managing S/W program
- tool life data
- quality data
- product history
- document update
9) Standard (ISO)
