Bagaimana Program CNC Yang Baik ?

Setiap Programer pasti menginginkan hasil program yang baik. Di sini akan ada sedikit tentang hal itu.

Diantara program yang baik yaitu:
1. Program yang menjadikan operasi mesin CNC lebih optimal (efektif) dan efisien.
2. Sanggup menghasilkan bentuk (geometri) benda kerja yang semakin komplek.
3. Mudah dan cepat dibuat.

Dalam membuat pemrograman ada beberapa hal yang harus dimiliki, yaitu:
1. Harus memiliki logika yang kuat.
2. Harus memiliki vision (gambaran/bayangan pikiran) yang baik dan kuat, yang bisa didapatkan dari experience (pengalaman)

KMDTM-KMDTE Mengadakan Kajian

Insya Allah pada tanggal 24 Februari keduan organisasi ini mengadakan kajian yang bersifat umum (bisa diikuti siapa saja).

Pada kajian ini akan dibahas tentang tanda-tanda hari kiamat dan insya Allah akan berjalan rutin setiap selasa, dan untuk waktunya insya Allah dimulai pukul 16.30 sampai selesai.

Rotary & Centrifugal Pumps

Rotary pumps operate in a circular motion and displace a constant amount of liquid with each revolution of the pump shaft. In general, this is accomplished by pumping elements (e.g., gears, lobes, vanes, screws) moving in such a way as to expand volumes to allow liquid to enter the pump. These volumes are then contained by the pump geometry until the pumping elements move in such a way as to reduce the volumes and force liquid out of the pump. Flow from rotary PD pumps is relatively unaffected by differential pressure and is smooth and continuous. Rotary PD pumps have very tight internal clearances which minimize the amount of liquid that slips back from discharge to suction side of the pump. Because of this, they are very efficient. These pumps work well with a wide range of viscosities, particularly high viscosities.

Centrifugal pumps differ from rotary pumps in that they rely on kinetic energy rather than mechanical means to move liquid. Liquid enters the pump at the center of a rotating impeller and gains energy as it moves to the outer diameter of the impeller. Liquid is forced out of the pump by the energy it obtains from the rotating impeller. Centrifugal pumps can transfer large volumes of liquid but efficiency and flow decrease rapidly as pressure and/or viscosity increases.

Introduction to PD Pumps

By definition, positive-displacement (PD) pumps displace a known quantity of liquid with each revolution of the pumping elements. This is done by trapping liquid between the pumping elements and a stationary casing. Pumping element designs include gears, lobes, rotary pistons, vanes, and screws.

PD pumps are found in a wide range of applications -- chemical-processing; liquid delivery; marine; biotechnology; pharmaceutical; as well as food, dairy, and beverage processing. Their versatility and popularity is due in part to their relatively compact design, high-viscosity performance, continuous flow regardless of differential pressure, and ability to handle high differential pressure.

Pump School® is made up of information from a variety of sources including manufacturers, governmental agencies, industry trade organizations, and common PD industry knowledge.

Angkringan (Penjual Nasi Kucing)

Penjual nasi kucing sudah sangat banyak seperti di daerah jogjakarta, bisa dikatakan dengan membeli nasi kucing kita bisa menghemat uang.

Tidak aneh jika yang mengkonsumsi makanan ini adalah para mahasiswa, di angkringan kita bisa juga membeli sebuah minuman seperti es teh manis, es jerus. Untuk nasinya sendiri ada yang berisi ikan teri, sambal, dan oseng-oseng, setiap penjual nasi kucing berbeda-beda dalam memberian isi lauknya. Sekarang penjual nasi kucing tidak hanya di kota jogjakarta saja, tetapi sudah sampai ke kota-kota besar lainnya.
