Since the launch of Industry4.0 initiative and with the desire to improve product development, product-lifecycle-management (PLM) technologies have been slowly evolving in the background.

Go into 10 different engineering companies and ask questions around how they handle and manage their tools?

Most probably you will receive 10 different answers. Why? Because everybody does it differently.

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.

Definition

Efficiency of machines has been an important topic in many areas of industry, at least since the introduction of the term "Industry 4.0". One of the challenges to improve the efficiency of industrial plants is the implementation of anomaly detection systems.

When you hear AR, for sure you are thinking about the heavy, chunky, massively overpriced Hololens and how you tried to somehow see something with the small field of view. We don’t even have to talk about the hard time you had trying to tap on virtual objects in the air.

Introduction

Developments and advancements in digital technologies have challenged traditional manufacturing and become the basis of what is known as the Fourth Industrial Revolution or Industry 4.0.

Background and Basics of ECM

Machining by ion dissolution, an opportunity for polishing implants.

Electro Chemical Machining (ECM) is a well-know technique: the shape of an electrode is reproduced in the part by current action.

Introduction  

With the development of high-resistance and refractory materials in the medical, energy and aeronautics sectors, a review of machining processes is urgently needed.

Introduction  

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.

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.

The first spinning-tool technology was developed jointly by Mori Seiki and Kennametal around 2008.

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

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.

Residual stresses are generated in a part during manufacturing which typically involves sequential thermo-mechanical processing including forming and heat-treatment steps.

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.

Model Based Definition is a new strategy of product lifecycle management in which the CAD models (Computer aided design) change from simple models with only the geometric data to extensive information sources containing all product manufacturing information (Alemanni, Destefanis, & Vezzetti, 2010).

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.

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.

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.

Manufacturing operations introduce Residual Stresses (RS) during sequential thermo-mechanical processes, like forming, heat-treatment and machining.

3D measuring probes prove to be extremely suitable for a quick check of the kinematics of a five-axis milling machine. The principle is based on measuring an object, by means of an accurate measuring probe, according to pre-programmed measuring cycles.
