Comment pouvez-vous vous assurer que les pièces usinées CNC répondent aux exigences des clients ?

The first key thing is to understand the true needs of the customer. Not all the needs are there on the contract or the drawings. And not all the needs are coming from customers. Those needs might come from the internal stakeholders or regulations, authorities, etc. One must understand what the different needs of the customer/stakeholders are and why the customer needs those. The next step is to establish a requirement management tool (it could be simply a spreadsheet) and put a person to always monitor the set of requirements and keep it up to date. And last, but not least, is to keep an eye on the validation and verification. Aim for early validation: be it simulation or making prototypes. And think ahead about the testing system.

It is critical to understand, monitor, and proactively address the real-time signs of inevitable tooling and machine tool wear. Operating metrics like torque, vibration, amperage draw, as well as a robust tool maintenance schedule requires continuous attention with qualified and skilled personnel.

Primary step in replicating a functional design for specific applications is often ignored. This entails studying the applications to create force diagrams and identify clusters of operating and functional criticality. The maxima and minimal limits for the forces should clearly be quantified in the context of the curvature, spatial and planar angles for crystallizing tolerances. OEM tolerances might not be the end all and be all for references. The MTBF (mean time between failures) and MTBA (mean time between assists during operations) as well as MTTR (mean time to repair a critical component in the jig) should be the deciding criteria for estimating tolerances whilst the force diagrams should guide us to change design.

Proper design or detailed selection is based on true detailed knowledge ,operation alternatives and customer needs awareness. then it comes to proper feed for updated requirements followed by clear follow-up of outputs to obtain successful investment opportunity and an improvement for CNC technology.

Understand the capability of the CNC meets the tolerance of the part. Test pieces manufactured to ensure capability of machinery

La condición la maneja el cliente, lo ideal es proponer 3 opciones (3 tipos de materiales, con su s respectivos costos). Nosotros debemos tener en cuenta, a la hora de la selección y análisis del material, el valor de hora hombre, valor de hora maquina, valor de herramental, y trabajo futuros que puedan ser compatibles con esas herramientas, para poder generar una amortización mas veloz de la misma. Esas son algunas de la variables a tener en cuenta, básicamente las que mas ponderan, por lo tanto hay que ser muy detallista y críticos en las mismas, ya que en estas se define todo.

In CNC machining, AI aids material selection by leveraging ML to recommend optimal options based on specific mechanical and thermal requirements. Additive manufacturing, combined with AI, enables innovative material design, optimizing structures for enhanced performance while minimizing waste. Virtual Reality and Mixed Reality (AR/VR/MR) enhance resource efficiency by allowing virtual testing of materials and prototypes, reducing physical waste leading to sustainability. MR applications in CNC machining can provide real-time insights, enabling operators to monitor efficiency and make immediate adjustments, contributing to sustainable practices by minimizing errors and optimizing resource utilization throughout the CNC machining workflow.

The client determines the conditions, and it is ideal to propose three options (three types of materials, each with their respective costs). We must consider several factors when selecting and analyzing the material: the cost of labor, machine time, tooling, and future work that may be compatible with these tools, in order to accelerate their amortization. These are some of the variables to consider, essentially the most significant ones. Therefore, we must be very meticulous and critical in these areas, as these factors define everything.

To guarantee proper functioning of a part, it is the appropriate selection of the material, this is carried out based on an analysis of the part and its interaction with the other parts, as well as the environment in which we will be working.

Asegurar la aplicación de un mantenimiento efectivo al equipo, considerando que la selección de materiales va implícita en la ingeniería se entiende que se tiene que respetar, la elaboración de la programación/diseño en CAD de la pieza más simple cumpliendo con las necesidades de la ingeniería; llevar un control de calidad efectivo con la utilización d e herramienta de medición certificada/verificada. Con esos pasos se asegura el cumplimiento de las necesidades del cliente.

In this regard, Generative AI and machine learning can enhance CNC machining quality control by automating certain aspects of inspection. AI algorithms can analyze real-time data from CNC machines, sensors, and measuring instruments to detect anomalies, deviations, or potential defects faster and more accurately than manual inspections. Machine learning models can learn from historical data to predict potential issues, enabling proactive measures. Additionally, AI-powered image recognition can assist in comparing actual parts with CAD models, assisting the verification process.

Coincido en todo lo expuesto anteriormente, añadiría que en función del tipo de mecanizado que se haya que realizar, invertir en herramienta de precisión, es una de las mejores inversiones en cuanto a calidad y mejora de procesos. Sobre todo si se trata de piezas en serie, evitar procesos intermedios o desplazamientos innecesarios, es otra forma de garantizar la calidad de las piezas producidas. Para garantizar la calidad de las piezas mecanizadas, la formación y la experiencia en el campo, son el camino a seguir.

An engineering blueprint serves as a binding agreement, explicitly outlining all necessary specifications and requirements. Upon accepting the task, suppliers are held accountable for adhering to these stipulations. A range of tools and methodologies are employed to guarantee compliance. Beyond the standard usage of gauges, calipers, and Coordinate Measuring Machines (CMMs), clients may supply bespoke tooling or fixtures for assembly fit assessments or expedited performance verification. To satisfy unique prerequisites, such as cleanliness and surface texture, the engagement of third-party entities for supplementary processing and metrology services may be necessitated.

Below are some effective methods via which you may gather customers viewpoint on your MVP Landing pages / Digital Surveys / Interviews / Campaigns / Beta Testing / Crowdfunding / Polls

Not always are specifications enough for success. A good working relationship with a Technical person and the Buyer are essential. Not always are drawings showing the Customers experiences and preferences. It's good to talk and discuss everything in detail.

A good customer-supplier interaction will end in the best product for the application, good communication will result not only in the application being able to do its job, but also in the trust you provide for your work.

Definitivamente la comunicación es elemental en cualquier proceso y más aún en una situación cliente-proveedor. Es una buena práctica Informar al cliente (si así lo desea) el estatus de su producto en los puntos críticos del proceso de fabricación. Una comunicación efectiva evita una buena cantidad de situaciones incómodas.

Es siempre ver y enfocarse en la necesidad del end users. Los medios herramientas para llegar a tener ese feedback continuo y en las necesidades de definición es lo que se debe trabajar en constante mejora.

Hay 2 tipos de prueba y validez, la primera es la ingeniería, que ahí es donde nace todo, y la segunda es la fabricación en base a la ingeniería. Ahí es donde se aplica todo el procedimiento de mecanizado y calidad establecido por la organización, para establecer estándares de eficiencia, producción y calidad.

Además de todo lo expuesto anteriormente, que coincido en todo. Añadiría que el planteamiento de la pieza, la experiencia y herramientas que aseguren la precisión necesaria. Son los que harán que nuestro trabajo cumpla con los estándares necesarios, para que nuestras piezas, cumplan con todas las tolerancias definidas en los planos.

By integrating ML and AI models, manufacturers can iteratively enhance CNC machining processes, ensuring ongoing adaptability and staying abreast of evolving trends and technologies. 1. Sentiment analysis algorithms can analyze customer feedback to identify specific areas for enhancement. 2. Predictive analytics models can anticipate potential issues based on historical data, enabling proactive adjustments. 3. Reinforcement learning models can learn from past project outcomes and suggest optimizations, considering the strengths and weaknesses of the machining process. 4. Natural language processing (NLP) algorithms can extract valuable insights from textual feedback, assisting a deeper understanding of customer requirements.

Mejora continua siempre!! toda la vida!!!una rueda que nunca debe dejar de rodar. Es la clave del éxito o de la continuidad del mismo dentro de toda estructura(equipos de trabajo, empresas, organizaciones, etc)

In my experience you should always begin with some cross functional review that looks at material requirements, for example material specification, thermal processing and post processing activities. As well as a review of inspection requirements and equipment or tools necessary to qualify the part definition. Then formulate a strategy considering all these inputs and any additional input from the customer regarding fit, form and functionally of the component.

Use the right cutting tools and recommend cutting settings to achieve the quality of the machined parts you desire. The machinist can fine-tune the cutting parameters to achieve the desired finish. Avoid using any blunt tools, wrong dimension tools, or tools not suitable for machined materials.

Sorry if I have missed this somewhere, but the process needs to ensure the product will not be over engineered to avoid unnecessary additional costs to the customer; and this must be demonstrated.

Process part is missing including initial proto, timeliness, risk analysis like availability of material, contingency and limitations definition.

Communication with the customer throughout the process is key for new products to ensure specs are clear and there is no ambiguity or bad assumptions during design review.
