Abstract Everyday practice of cutting process planning requires reliable chipbreacking and this is particularly true when machining difficult-ti-machine materials as austenitic stainless steels. The use of pressed-groove type of chipbreakers prove to provide a partly solution of the problem since their utilization unavoidably leads to increasing cutting force and chipping of the cutting edge. The use of clapped-on chipbreaker seems to solve these problems. However new design and application problem arise. This paper deals with the analysis of these problema and offers a methodology for it resolving. As a result, a new type of a clamped-on chipbreaker has been developed.

The Mining Industry is one of the pillars of national economic development. In this industry, heavy equipment plays an important role in the coal mining process in Indonesia. By using heavy equipment must be well structured, so that the project can run easily without any obstacles. This research aimed to evaluate the cause of the low-value OEE of the Excavator Hitachi EX2500-6 of EX157 and EX158 units and determine the way to repair so that the equipment performance can be improved. This research uses descriptive quantitative approach with value analysis methods Overall Equipment Effectiveness (OEE). The result of OEE values were analyzed using losses classification method so that the occurrence of loss factors can be found and root cause analysis performance using a causal diagram/fishbone diagram and then make any improvement recommendations that can be done by using 5W1H analysis. Based on the research results, the OEE values of two excavators were calculated and were compared with the benchmark values. The values of OEE were found to be 84% for EX157 units and 68% for EX158 units. The low value of OEE on EX158 caused by unscheduled maintenance time losses amounting to 1188.3 hours. The high of time loss is influenced by trouble on Machine Frame, Structure, Body, and Cab components amounted to 60.9%. The root causes of the losses derived from the availability of external mechanics, the competence of mechanics, the availability of spare parts, and the implementation of condition monitoring was not optimal. While remedial steps can be taken by giving technical training program for mechanics as maintenance practice methodology.

ABSTRACTIn this paper we will discuss a new type of field effect transistor, a vacuum FET, where the usual channel material is the vacuum rather than a semiconductor. This new device is based on Field Emitter Arrays (FEA) which are inherently submicron structures. That is, the field emitters themselves must have dimensions less that 0.1 micrometers in order to generate the high electrostatic fields necessary for electron tunneling, and the control gate (or extraction electrode) must be very close to the field emitter tip in order to generate these high fields with reasonable voltages. Consequently, this new “FET” is the first of a new class of vaccum electronic switching devices based on microfabrication techniques, and susceptible to circuit integration.

Rotational rheometers are used to measure paste properties, but the test would take too long to be useful for quality control (QC) on the job site. In this paper, a new type of rheometer is proposed based on a one degree of freedom (DOF) micro-electro-mechanical systems (MEMS)-based motion stage. Preliminary data will be presented to show the capability of the system to measure the viscoelastic properties of a paste. The parallel plate geometry rheometer consists of two plates, which move relative to each other to apply a strain to the material to be tested. From the stress measured and the strain applied, the rheological characteristics of the material can be calculated. The new device consists of an electrothermal actuator and a motion plate. For the rheological measurements, the device is designed to generate the shear stress up to 60 Pa and maintain its stiffness to less than 44 N/m. With these features, the device uses a square plate of 1.5 mm x 1.5 mm to provide enough area for a few micro-liter level volumes. The motion of the square plate is monitored by a capacitive sensor at the end of the oscillating plate which has a resolution of 1.06 μm. When a reference cementitious paste, Standard Reference Material (SRM)-2492, is placed between the oscillating plate of the presented motion stage and a fixed plate, the reduction in the displacement of the oscillating plate is monitored showing that the presented motion stage is reasonably designed to detect the response of the reference cementitious paste.

Maintenance Work

Maintenance Work Orders (MWOs) are a useful way ofrecording semi-structured information regarding maintenanceactivities in a factory or other industrial setting. Analysisof these MWOs could provide valuable insights regardingthe many facets of reliability, maintenance, and planning.Information such as which maintenance activities consumethe most work hours, identification of problem machines,and spare parts needs can all be inferred to some degreefrom well documented MWOs. However, before one canderive insights, it is first necessary to transform the data inthe MWOs (generally some form of natural language) intosomething more suitable for computer analysis. NIST previouslydeveloped a computer aided tagging system that allowsfor the quick identification of key concepts within the naturallanguage of the MWOs, and a protocol for categorizingthese concepts as solutions, problems, or items. Using thisannotation method, this paper investigates machine learningmethods to gain insights about work hours needed for variousmaintenance activities. Through these methods, it ispossible to explain the factors captured in the MWOs thathave the strongest relationship with the duration of maintenanceactions. The workflow of this research is to firstbuild strong data driven models to classify the duration ofany maintenance activity based on the language and conceptsgathered from the associated MWO. Sensitivity analysis ofthe inputs to these classifiers can then be used to determinerelationships and factors influencing maintenance activities.This paper investigates two machine learning models - aneural network classifier and a decision tree classifier. Inputfeatures for the classifier were the annotated concept tags for solutions, problems and items derived from MWOs of anactual manufacturer. This process for gaining insights can begeneralized to various applications in the maintenance andPHM communities.
