CNC Machining

CNC stands for Computer Numerical Controlled and is used to automate the machines tools for the production of components or products. The CNC machining involves end to end design of the component with CAD CAM systems. The CAD/CAM systems create commands which can automatically operate the CNC machines.


Following is the process of CNC Machining:

1. Create a model/blue print of the component to be produced / machined

2. Create a process of flow of the raw material to the final component

3. Write CNC programs for the system for machining

4. Schedule a run time for the CNC machine

5. Check the quality of the raw materials to be used

6. Set up the CNC machine

7. Produce some samples of the components to be produced

8. Check the samples for quality and design

9. Adjust the settings based on the check on samples

10. Run the machine to produce with components with continuous quality checks

11. Final inspection


There are numerous benefits of using CNC machines for production

1. You can achieve high volumes 

2. Once standardised, the program can be used for repeated production of a component

3. Low cost of production

4. High quality production is achieved as there is little human factor involved

5. Cycle time of production is reduced with automation

6. Repeat customers

There are many companies in Australia which supply high precision products to manufacturing houses. The advantage of outsourcing some of the components to a vendor are that you do not have to focus on components which are required in high volume, require high quality, but come at a low cost and may require considerable capital. Such components can be easily outsourced and bought from companies which are experts in precision engineering for repeated production.


One such company is Hargo Engineering - which specialises in high precision machining for repetition engineering. You can visit their website for more information.

Microfabrication of biomedical lab-on-chip devices. A review/Biomeditsiiniliste kiiplaborite valmistamine.

1. INTRODUCTION Lab-on-chip technology focuses on the development of hybrid devices, which integrate fluidic and electronic components onto the same chip [1-5]. They are devoted primarily to liquid sample testing and handling. Such devices reduce laboratory processes in a manner competitive to bench-top instruments. Lab-on-chip technology emphasizes integration, chip programmability, increased sensitivity, minimal reagent consumption, sterilization and efficient sample detection and separation. Lab-on-chip functionality includes sample handling, mixing, filtering, analysis and monitoring. A typical lab-on-chip device contains microchannels, which allow liquid samples to flow inside the chip, but also integrates measuring, sensing and actuating components such as microvalves, microfluidic mixers, microelectrodes, thermal elements, or optical apparatuses. Some commercial lab-on-chip devices incorporate electronics that operate their apparatuses (Fig. 1). The lab-on-chip devices are c

wifi paddle boat.

Summer is in full swing in Oklahoma and the kids, grandkids, nieces, nephews and, well, just about everyone we know is in Lake Zumwalt to cool down. My wife has purchased enough pool toys to fill Lake Zumwalt, so I figured I would join the pool toy fray with WiFi Paddle Boat.WiFi Paddle Boat is a paddle boat controlled via wifi using rubber a smart phone, tablet or other touch enabled device. WiFi Paddle Boat creates a wifi access point (much like the small sport cameras) that you connect to via your wifi enabled device wifi settings. Then, using your wifi touch enabled device web browser, you simply navigate to the WiFi Paddle Boat web page and off you go! The controls for WiFi Paddle Boat are identical to those of my "Lady Buggy" and "Santa Sleigh" designs so it's easy for the grandkids to operate.A word of caution; I designed WiFi Paddle Boat to be "splash resistant" not "water proof", so if a rogue wave, grandchild, niece, nephew, et

Analysis of mechanical seal leakage Cause

In centrifugal pumps and reaction kettles, the seal between the rotating pump shaft and the stationary casing is simply referred to as a shaft sealing device. Currently, centrifugal pumps and reaction kettles are commonly used for packing and mechanical seals. Mechanical seals are widely used because of their advantages such as small leakage, long service life, low power loss, no need for frequent maintenance, and low environmental impact. The manufacture of mechanical seals is complicated and requires high precision. During operation, the inspection personnel are required to find problems in time and deal with them as soon as possible, so as to extend the service life of mechanical seals. Vibration, heat and smoke of mechanical seal 1. The end pressure is larger Treatment measures: (1) Adjust the position of the moving ring base to reduce the specific pressure of the end surface; (2) Replace the mechanical seal spring to reduce the end surface specific pressure. 2.
