“…Therefore, whenever possible, tests should be automated. An adequate machine for performing this task is a 3-axis Computer Numerical Control (CNC) system [21]. These machines have 3 axis of independent movement and are ubiquitous in several industries (e.g., ranging from 3D printers to assembly lines).…”

The current design paradigm of car cabin components assumes seats aligned with the driving direction. All passengers are aligned with the driver that, until recently, was the only element in charge of controlling the vehicle. The new paradigm of self-driving cars eliminates several of those requirements, releasing the driver from control duties and creating new opportunities for entertaining the passengers during the trip. This creates the need for controlling functionalities that must be closer to each user, namely on the seat. This work proposes the use of low-cost capacitive touch sensors for controlling car functions, multimedia controls, seat orientation, door windows, and others. In the current work, we have reached a proof of concept that is functional, as shown for several cabin functionalities. The proposed concept can be adopted by current car manufacturers without changing the automobile construction pipeline. It is flexible and can adopt a variety of new functionalities, mostly software-based, added by the manufacturer, or customized by the end-user. Moreover, the newly proposed technology uses a smaller number of plastic parts for producing the component, which implies savings in terms of production cost and energy, while increasing the life cycle of the component.

“…They work by having a coupled computer following a precise script telling the machine the movements that have to be done. The adopted setup uses an industrial 3-axis CNC machine [21] with a capacitive "finger" probe (please see Figure 9c) attached in the gripper part as depicted in Figure 9d.…”

“…Thus, only few samples can be measured with a CMM. By conducting tactile measurement inside the lathe [11], the possible sample size can be increased, but the required measurement time still exceeds the production time.…”

Temperature drifts, tool deterioration, unknown vibrations, as well as spindle play are major effects which decrease the achievable precision of CNC lathes and lead to shape deviations of the processed workpieces. Since currently no measurement system exists for precise, in situ, 3D shape monitoring, much effort is required to simulate and compensate these effects. In this article, we propose an optical measurement principle for first part quality manufacturing. The absolute shape, meaning the diameter and surface profile, of the workpiece is determined from its tangential velocity and the surface distance. In order to allow keyhole access, both measurands are determined simultaneously with a single sensor. Measurements inside a metal working lathe show that the standard uncertainty for the absolute shape measurement is below 1 μm. The measurement uncertainty is nearly independent of the lateral surface velocity and roughness. The in situ measurements are compared to measurements with a tactile coordinate measurement machine for reference.

“…The main disadvantage lies in the high cost of purchase, prompting the exploration of various alternative methods. Examples include a simple probe for measuring diameter from a single point [7] or a measurement system based on a cutting tool, as described in [8]. This system operates by generating an electrical impulse as a result of contact between the insert and the workpiece.…”

One of the key aspects of the automation of machining processes is the elimination of manual measurements. This is crucial in the production of precision parts, where the absence of in-process control can lead to an increased number of non-compliant parts, resulting in financial losses for the company. In addition to economic considerations, environmental care is a fundamental requirement for manufacturing companies. While many efforts focus on finding environmentally friendly coolants or reducing machining time, researchers often overlook the impact of the measurement method on the balanced development of machining. The conditions inside CNC machines are quite demanding in terms of maintaining measurement stability. For this reason, this paper presents a comparative study of two types of machine inspection probes. The influence of the measurement axis and the effect of returning the probe to the magazine on the accuracy of the measurement were examined. This study revealed that the probe with a kinematic resistive design has a higher measurement uncertainty (2.7 µm) than a probe based on strain gauges (0.6 µm). This paper emphasizes the positive impact of the conducted activity on the sustainability of machining, highlighting benefits such as resource savings, energy savings, and positive effects on the health and safety of operators.
