kita eksekusi di mesin nah ini saya saya
contohkan membuat dua program yaitu k
sama ngebur ya kita simulasikan dulu
kita
sebel Apakah sudah benar atau atau belum
ya Oke kita
play oke nah kurang lebih sama seperti
ini Programnya sudah benar Oke saya akan
mengambil Salah satu program ya yaitu
program kontur Mengapa saya ambil satu
tidak kita ambil semua programnya karena
di sini program kontur dan juga pack
drill itu berbeda alat potongnya
kalau kontour menggunakan nmil diameter
8 kalau P drilnya menggunakan bur
diameter 6 makanya kita pilih satu-satu
Kalau mungkin ini toolpadnya lebih dari
satu sedangkan tool yang digunakan sama
bisa kita ambil sekalian beberapa
toolpad tapi kalau toolnya berbeda ini
Emil 8 sama ber diameter 6 maka kita
sebaiknya ambil satu-satu Oke saya
contohkan saya ambil program konturnya
caranya bagaimana
yang pertama kita tekan G1 atau post
selected Operation
oke di sini kita centang saja karena
ekstensinya jenis file-nya sudah
dnc kita tekan oke nah Ini penting
sekali ya karena biasanya kalau
settingan default di sini ada konfirmasi
not all Operation ya Yang Yang kamu
ambil nah have been selected yang kamu
pilih di sini ditanyakan lagi Apakah
anda akan mau all Apakah mau ngambil
program semuanya di sini settingannya
otomatis Yes nah ini hati-hati kalau
kita pilihnya Yes maka semua program itu
sudah terpilih karena kita hanya mengil
to makanya kita tekan no ya
kita hanya mengambil satu
toolp nah kita letakkan di flash disk
Nah ini USB Dri a kemudian kita pilih
nama misalkan namanya kontur
Oke kemudian kita
save maka keluarlah NC kodenya ya Akan
tetapi ncode ini tidak bisa kita
jalankan di mesin kita harus edit dulu
oke yang pertama di sini semua judul
yang berwarna hijau ini sebaiknya
dihapus kalau enggak dihapus enggak
apa-apa ya tapi ini untuk menghemat
ruang saja seperti keterangan nm
diameternya material aluminium nah ini
dihapus saja Kemudian ini perhatikan ini
ada O sama 04 kali 0 4 kali kita hapus
menggunakan EMP angka yang berbeda
selain 1 2 3 4 misalkan 2 1 1 4 oke yang
kedua t sama M ini dihapus saja karena
di sini untuk pergantian tool Ching
pergantian tool otomatis pasangannya
menggunakan g43 sama H ya untuk tool
offset-nya video lengkapnya di video
yang smart sense yang sebelumnya cara
mengambil NC kode ya ini tidak saya
jelaskan panjang lebar ya
Oke ini kita simpan ya oke kemudian kita
close nah kemudian flash disknya kita
ambil ini flash disknya kita ambil kita
masukkan ke
mesin Oke kita masukkan
oke nah
[Musik]
langkah pertama sebelum menjalankan
mesin
atau memanggil program ya eksekusi
program di mesin ya syaratnya ada empat
yang pertama syarat yang pertama adalah
mengecek hasil
settingan mengecek hasil settingan tadi
benda kerjanya ya di gambar itu saya
setting di tengah-tengah ya Nah maka
sebelum kita jalankan mesin kita cek
hasil settingannya dulu caranya kita
tekan program mdi atau tombol
mdi kemudian kita pilih
program masukkan program untuk ngecek
hasil settingannya yaitu
g90
g54
G1
x0
y z
30
f2000 kita input sebelum kita cle start
kita cek dulu g90 g54 G1 Nah kalau benar
kita nolkan semuanya baik dari fitr dan
juga
spindelnya yang ketiga ini juga di
nolkan atau dikasih kecepatan 0,01 baru
kita SLE start tangan kiri standb di
tombol emergency kalau hasil
settingannya salah Oke kita ar Nah kita
bisa menggerakkan mengatur gerakan
nilnya menggunakan F Ini
oke Ya kita putar maka dia akan turun
ya Nah letaknya di sini di tengah-tengah
nmnya sudah di tengah-tengah benda kerja
ketinggiannya ini sekitar 30 karena ini
sekitar 20 mungkin ini ya pas Min 30-an
ya Saya ee enggak punya yang 30 tapi
kurang lebih sama oke nah karena
settingannya sudah benar maka kita
nolkan mesin Hero Z plus dia naik
dulu
x+ y plus kalau sudah naik Baru kita
pakai kecepatan sat
oke nah syarat yang kedua
setelah ngecek hasil settingan syarat
yang kedua kita cek skednya nol apa gak
atau kecepatan paling Rah rendah apaak
Oke 50 Syarat yang
ketiga vatnya
nol nol syarat yang keempat
rapidnya dibuat sekecil mungkin tapi
kalau rapid yang di mesin ini karena ini
masih e belum standar yang ke mesin
produksi ini harus dibuka
25% atau mendekati nol yang paling kecil
atau
0,01 syarat yang
kelima yaitu single wajib dihidupkan
Saya ulangi lagi lima syarat ketika
menjalankan program yaitu Cek hasil
settingan
mdi
kemudian
spindelnya kecepatan paling rendah atau
50% yang ketiga Fit rate-nya
dinolkan yang keempat rapidnya
0,01 yang kelima single wajib nyala di
sini nyala kuning nah oke le fsinya
untuk apaingle itu artinyaingle bl
membaca program setiap sat baris sat
baris Mengapa Harus satu baris karena
kalau ini tidak hidup ya bisa jadi
ketika programnya salah atau setting
Bend kerja salah diasung Jalan otomatis
langsung
menyay khawatirnya nanti bisaus
setelah itu terakhir kita
Jal kitanya di dnc dnc ini adalah direct
NC atau memanggil program dari memori
eksternal kalau auto memori internal
mesin tapi kalau dnc memori eksternal di
mana di USB atau flash disk ya oke
setelah di dnc kita pilih
program setelah kita pilih program kita
cari nama file-nya di mana di folder
kita pilih
Dir di folder ini kita cari namanya tadi
namanya Apa nama Programnya apa kontour
Oke kita
turunkan cari Nah ini
nih kontur kalau sudah keblok warna
kuning bisa kita input oke cek lagi nama
programnya kontour
oke ya
oke sebelum kita Se lagi ya kita lebih
waspada lagi yang pertama midnya 50%
pitetnya 0 kemudian rapitnya
0,01 single-nya nyala oke nah kalau
sudah tangan kiri kita letakkan di
eh tombol emergency standby tangan kanan
pegang cle start kita Nyalakan cle
start maka dia akan kebaca satu banis
nah ini fungsi dari single block kita
SLE start lagi kebaca satu baris lagi
nanti pada M3 s3000 dia akan berputar
pada baris kelima
ini nah ini belum masih program pembuka
nah ini dia
berputar I kan Nah
S3 kemudian kita turunkan lagi maka dia
harus Berarti z25 kalau tidak berhenti
di atas ya 25 mili masih turun terus
kita tekan ensinya nah
Nah itu 25 mili kemudian turun lagi fit
l-nya pada jarak 10
mili nah 10 mili kalau sudah benar ini
di 10 mili bisa kita buka spindelnya
100% maka dia akan meningkat
kecepatannya
Oke kalau sudah 100% single blocknya
Gantian kita matikan supaya dia jalan
otomatis terus single blocknya kita
matikan Oke setelah itu bisa kita cle
start nah dia akan nyala terus hijunya
sekarang gerakannya kita kendalikan
menggunakan
Oke gitu ya Oke kita kend kendalikan
bkan kita buka pelan-pelan saja
Oke 60% atau 70% Oke kita lihat
sana pada Z ini
0, du nanti sampai z-8 total g-nya oke
oke dia 0,1 saya pakai gerakan ranking
jadi dia semakin gerakan XY sambil z-nya
semakin turun sambil
turun
ininya turun
ya ini sudah mulai nyayar turun ya ini
kan mulai nyayar supaya lebih aman Bisa
kita
tutup kemudian kita hidupkan kolennya di
sini kolen pakainya cooling
[Musik]
Oke Maaf bisa lihat
Oke kita buka 100% gak apa-apa
Oke kalau mau lihat
posisinya posisi di absolutnya nah dia
baru jalan di main 1 mili nah ini mulai
nyayat totalnya nanti sampai berhenti
pada z-8 mili lihatnya di posisi Nah
sudah mulai nyayat ya suaranya ya
ngengu Nah itu sudah mulai nyayat Nah
kita lihat dulu sampai
selesai ketika machining atau
menjalankan program P ini wajib dipegang
Mas Ya wajib
dipegang Mengapa bisa jadi ini
programnya error atau nabrak dan
sebagainya Kalau salah kita masuk lkan
maka dia akan berhenti I kan nah tapi
kalau aman ya biar jalan
aja
ng bisa diung ke
sana kelihatan ya
oke
[Musik]
[Musik]
jelas Ya
jelas
Pak ditahan dulu apa namanya
itu nah ini sudah mau selesai pada
kecepat pada kedalaman z-nya -7,9 nanti
selesai pada 8
ya z-8 Nah ini terakhir Dia gak turun
lagi kita lihat pergannya
sana Nah kalau sudah selesai otomatis
nanti dia akan naik
sendiri naik sendiri
kemudian spindnya berhenti dan
juganya mati sendiri kali ke home
mesinnya Nah sudah
selesai Nah kalau masih nyala kennya Oh
mati ya karena
M9 kita lihat ini
hasilnya kitaak
dulu Nah ini bisa dilihat tadinya
