Machining electrically conductive ceramics with spark erosion (EDM)
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.
Choose the right endmill to optimise your milling process
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.

Carbide inserts Wear Failure modes.
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.
Why we can machine graphite with Diamond tools.
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.

Impact Hammer Test (TAP Testing)
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
Real-Time Production Scheduling in Job-Shops
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.
CAD, CAM and Verification
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.

VR Training
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.

Milling with Ceramics
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.

Sensory Tool Holder
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.
