Impact of a Robot Manipulation on the Dimensional Measurements in an SPC-Based Robot Cell

In our study a robot was used to deliver objects for measurement into the Equator gauging system. To investigate the robot’s manipulation influence on dimensional measurements, the robot’s tasks were divided into basic functions. Based on these basic functions, nine different robot-manipulation scenarios were defined, i.e., from zero to full robot manipulation, for two measuring objects (named Magnet and PKR) and six measurement characteristics (rectangular and spherical). The robot’s manipulation influence was determined on the basis of the statistical parameters Cp, R, and the 6σ obtained from a measurement system analysis (MSA) type-1 study. The results show that the degree of implemented manipulation of the robot affects the scattering of the measurement data. However, the effect is much more pronounced in the case of length measurements than with spherical geometries. Different measuring methods (touch-triggering or scanning measurement mode, number of sampling points) were used, which showed similar measurement data. This directly indicated the influence of the robot’s manipulation on Cp, R and 6σ. Increasing the degree of the robot’s manipulation decreases the Cp value and increases the R and 6σ values for the length measurements. There is no such pronounced course in the spherical geometries, where the values of Cp, R and 6σ remain approximately the same. The main influential factor for decreasing the Cp value with increasing robot manipulation was the angular misalignment of the object’s orientation in the fixture.

Quality Assurance for Operating Room Illumination through Lean Six Sigma

Since every mistake made in the healthcare industry can cause permanent harm or even death, some fundamental requirements should be considered when planning and designing operating rooms. Lighting is one of the most important ergonomic factors, especially for operating rooms. This paper investigates the integration of the lean approach and six sigma in measuring the efficiency of LED technology, which can also be regarded as a factor affecting the operating room efficiency. Measurement System Analysis (MSA) and Gage Control methods were applied to determine measurement variability in operating room illumination measurement process. Repeatability and reproducibility (%R&R) was found 12.89%. After calibration, %R&R value was found 8.21%, which implies that calibration helped reduce variability.

PENERAPAN METODE MEASUREMENT SYSTEM ANALYSIS GAGE R&R PADA PENGUKURAN PRODUK BASE PLATE MAGAZINE

In the current era of globalization, the perceived quality competition globally is manufacturing. Manufacture industry competition makes companies must concentrate on product quality. and the quality of the factors affecting the product is wrong, such as human resources, tools / machines, and the environment can also cause product quality. And one of the companies engaged in the manufacturing industry, namely PT. APT has a problem with the quality measurement of the dimensions of size on one of the products made, where the product can’t be accepted by the customer and declared reject on all the number of products sent. There are indications of QC checking errors within the company so that reject products are accepted as acceptable. The purpose of this research is to find out what are the main causes of goods declared acceptable internally within the company and when it arrives at the customer is declared reject. And find solutions to how such mistakes do not happen again. To solve this problem, this study uses the MSA (Measurement System Analysis Gage R&R) method which has the advantage of knowing the cause of quality problems in detail whether from the people, tools, or supporting factors in a measurement. So that mistakes that occur before do not happen again and the company can run more effectively, efficiently and consistently in measuring and checking.
