Laser Powder Bed Fusion (LPBF) Process - Productivity Science

Laser Powder Bed Fusion (LPBF) Process

The LPBF parameter space consists of laser power, scan speed, laser spot size, scanning strategy, feedstock, part geometry, and machine conditions. The selection of process parameters determines the resulting microstructure and component properties.

Various libraries of process parameters for a given machine and material have been determined through physical testing by AM suppliers or individual laboratories. An integrated computational materials engineering (ICME) approach reduces the amount of physical testing and informs design engineers about detrimental performance expected for specific process parameters.

How To Increase Production In Knitting Floor

Posted on July 15, 2014

Machine Speed:

Production per hour depends on the speed of the machine, the machine rpm. But higher speed imposes excess tension on yarn. Excess tension on yarn can increase the breakage of yarn which is not desired. So technology development is important in machine as well as operation.

Process Machine Effort Industrial Engineering - Lessons - IEKC Online IE Course Module

Industrial Engineering is System Efficiency Engineering. Its main areas are Machine Effort Industrial Engineering and Human Effort Industrial Engineering. Narayana Rao K.V.S.S., Industrial Engineering Knowledge Center.

Machine Effort Effort Industrial Engineering - Design of Machine Effort for Overall Process and Equipment Effectiveness and Efficiency

In each of the operations shown in the flow process chart, namely, processing, inspection, transport, temporary storage (due to delay in next operation) and permanent storage, there is involvement of machines and men. There are machine effort and human effort. Industrial engineering is primarily focused on machine effort as engineers' activity and additionally developed science and engineering of human effort. So there are process machine effort industrial engineering and process human effort industrial engineering as main components of process industrial engineering.

To do machine effort industrial engineering, industrial engineers need to have full knowledge of the machine elements, various operations that can be done on the machine and the process plan of the job. Then only they can look for more productive alternatives from new engineering development, new machine accessories that are being offered by vendors and from their internal learning and creative breakthroughs.

Lessons related to machines, operations and process planning was included in process industrial engineering complete module. The productivity analysis of each operation in flow process chart related to machine effort and other engineering items is presented below.

A separate module covers process human effort industrial engineering in details.
