The commission of the machine tools manufacturers had commissioned Cetim to carry out an instruction file around the problems of filtration and follow-up of machining machines.
A study on filtration was decided, with two working phases including the research of information and the preparation of the test phase, object of this synthesis.
Technological watch: Materials used in the tooling field : High Speed Steels - Coatings and additional treatments
To improve their performance and extend their service life, HSS tools can benefit from a number of additional treatments, such as conventional heat treatments, water, air and oil quenching, but also using new processes such as laser quenching or cryogenic treatments, as well as the coating of the active areas - more specifically the tips and cutting edges - by depositing titan
Robots are often part of cells where high precision tasks may be performed, such as assembly, welding, pick and place that are often complex and repetitive. Being an integral part of the Industry 4.0 new paradigm, collaborative robots have started to be integrated in smart manufacturing eco-systems.
The choice of steel grade depends on a number of practical application factors, such as toughness (resistance to crack initiation and propagation), hardness (resistance of the material to penetration), thermal fatigue resistance (resistance to the effects of successive heating and cooling which can generate cracks), which can be translated into the simple application questions
In-process inspection is the process of investigating a produced feature within the same process flow, directly after the feature has been machined. In-process inspection is carried out on the same machine and in the same setup which is used for producing the feature. This process consists of a visual inspection to check the surface finish as well as a dimensional measurement of the feature.
Suppose the most critical asset of an assembly line is incapable to handle a temporary surge of demand or worse it is out of order. One solution to address such a scenario would be to have a fully automatic and versatile Plug and Produce (PnP) system, ready on standby that can be summoned to the assembly line.
Springs are typically delivered in bulk and feeding them into an assembly line is often a considerable challenge for factories engaged in assembly and installation activities. The reasons behind this difficulty are numerous since springs as a shape have some distinct features. For comprehension, some of the main features of the spring have been listed below:
The following practical guidelines were established after consultation with the Machining4.0 consortium based on many years of experience with helping companies.
The life of a carbide drill bit or cutting tool is measured in fractions of a millimetre, while the tool itself could be over a hundred millimetres long. There is good reason for this, but nevertheless and end-of-life tool retains significant value due to the materials and energy used to produce it.
Many manufacturing companies have identified a critical manual quality visual inspection check within their manufacturing workflow as a process that is repetitive, time consuming and open to errors. In the aerospace sector, for example, every part that is manufactured is machined in pairs, left and right.
Adaptive machining is the adaptation of NC programs to accommodate part to part variation enabling more stable and consistent production of complex or variable geometries. Repeat component manufacture requires a repeatable machine and process to ensure the product is machined to the same standard every time.
Robotic process automation (RPA) constitutes a set of software technologies that facilitates the building and deployment of software robots (bots) that mimic human actions when interacting with graphical user interfaces and other digital systems. Actions, such as opening a file, moving the mouse, filling in form fields, etc.
Let’s cut to the chase: not every SME needs extra MES functionality to link the office and the shop floor, provided that the available ERP modules and possibilities are fully utilised. Because ERP makers also want to claim a part of the MES market, many traditionally have a shop floor module at their disposal.
In today's production systems, machine breakdowns are very severe. They not only generate unscheduled downtimes with related expenses and dissatisfied customers, but they also wreak havoc with staff scheduling (additional shifts) and warehousing (additional storage), as well as quality deterioration (scrapped components) and subsequent machine warm-up periods.
You may have heard the terms machine learning and AI being used interchangeably, but what are they exactly? Machine learning is broadly speaking the use of statistics to make predictions, while AI is more concerned with behaviour (e.g. playing games (like AlphaGO), visual perception, speech recognition, decision-making, and translation between languages).
As a machining company, are you considering investing in a new CAM system? Then you'll certainly want to consider the following points of interest!
CAM (computer-aided manufacturing), like CAD (computer-aided design), is done via customised software packages. There are some relevant aspects to consider when buying a new CAM system.
CAM or CAD/CAM
The emerging Industry 4.0 paradigm facilitates intelligent factories where machines, robots and human workers work side by side. Collaboration between these entities in a factory environment allows having higher throughput with the ability to perform complex processes which needs multiple skills from robots as well as humans.
The use of ceramic cutting tools is on the rise, that news is less dramatic than it seems, because solid ceramic end mills and inserts are usually easier to use than carbide tools. Changing to using ceramic cutting tools doesn’t need really any special process changes. Contrary to what people might think about ceramic tooling.
How does it work?
By use of a head mounted display and a set of controllers, the user is placed in a virtual environment where they can practice, learn and improve their skills. The user will enter a scenario in which they have to perform a set of tasks to reach a goal. The scenario depends on the type of training.
Computer Aided Design (CAD) and Computer Aided Manufacture (CAM) software has been developed since the late 1950s and is an essential component of modern manufacturing. The term CAD covers a range of applications from 2D drafting packages to full 3D design packages with simulation and analysis tools.
Small and medium machining shops are often arranged as job-shops. In a job-shop the production is usually done in small batches, and the machines are arranged in functional units, or cells (milling cell, drilling cell, etc). Each part or product to manufacture needs to follow a sequence of operations (a route) to be performed in different machines.
Tap testing, also known as modal testing, is an experimental method that is used to excite the machine-tool system in order to extract its harmonic information such as natural frequencies, modal masses, modal damping ratios and mode shapes. This is normally done in static conditions, using the impact hammer as the excitation mechanism, and an accelerometer as the sensor. In theory, the tool t
Graphite has specific properties that make machining a challenge. It’s strong, but also brittle, and is susceptible to chipping if not handled properly. Cutting Graphite (or carbon) is different from cutting Metals. Metal exerts plastic deformation when a tool edge cuts it producing a curl or chips.
Tool wear describes the gradual failure of cutting tools due to regular operation. It is a term often associated with tools used for example on turning, milling, drilling and other types of machining operations where chips are made. We could also say “We started with a new cutting edge and at the beginning of the operation everything was working well.
Industry 4.0 is built around the exchange of information between machines and higher-level systems. Connected machines and far-reaching digitisation ensure that manufacturing companies can make their production lines more flexible, secure and autonomous. For machine builders, connected machines offer the potential to develop digitally supported services.
Solid carbide endmills are the most commonly used tools in almost every machine shop. Process engineers are always concerned with productivity gains by reducing the tooling cost, machining time and bring down the cost per part to increase the margins. The selection of the machining conditions either rely on the experience of the operator or the recommendations from the tool manufacturer.
Because of their extreme hardness, ceramic materials and their composites are very popular for mechanical applications that are susceptible to wear and tear due to heavy loads. The other side of the coin is that conventional techniques do not usually suffice to work these materials. Some are even impossible to grind, because oxides deposit on the grinding wheel.
A sensory tool holder is an inline tooling adapter that is capable of measuring three different dynamic responses within the tool – these being the bending moment, the tension and the torsion. With applications to both milling and turning operations, a sensory tool holder can continually collect data during a given operation and wirelessly transmits this data to a nearby laptop.
