Understanding MMC and LMC in ASME Y14.5: A Detailed Guide

Aygün Karaköse
in Theory
7 0 Expert
In geometric dimensioning and tolerancing (GD&T), MMC (Maximum Material Condition) and LMC (Least Material Condition) are fundamental concepts that help ensure proper part fit and function during manufacturing and assembly. These concepts link the physical size of a feature with its allowable geometric tolerance, enabling more flexible yet controlled manufacturing.

This tutorial explains how to calculate the percentage of a specific alloying element (e.g. C, Mn, Cr, Ni) in a weld bead based on contributions from base metal, filler metal, and other additives. This calculation is critical in welding metallurgy to predict the final chemical composition of the weld and ensure mechanical properties meet standards.

Automated Product Structure Creation in CATIA V5 Using Excel + Smart Property Update In this video, we demonstrate a complete workflow for generating a product structure in CATIA V5 using a simple Excel table. By entering the part number, description, revision, and assembly level, the macro automatically builds the correct hierarchical structure inside CATIA. We then create a basic part, define its dimensions, assign material and sheet metal thickness, and use a custom macro to update part properties like material, thickness, and revision directly from the Excel input. The video also shows how parameter changes are reflected instantly through automated updates — keeping your design, documentation, and data fully synchronized. 🎯 Ideal for design engineers working with large assemblies and standardization workflows. 🔧 Key Features: Auto-generation of CATIA product structures from Excel Sheet metal part creation with parameter definition Automated metadata (properties) update Live synchronization of parameter changes

In this video, we dive into a powerful VBA macro designed to streamline file management for CATIA CAD projects. Watch as we demonstrate how to automate renaming and reorganizing parts and assemblies within a hierarchical folder structure. With audio commentary, we explain each step, making it easy to follow along! What You'll Learn: Tree Navigation Commands: Use Collapse All, Expand All, Select All, and Unselect All to manage file hierarchies efficiently. Rename Command: Replace prefixes like "XX", "XX XX", or "XX XX XX" with custom values (e.g., "01 00 00 000" to "08 02 01 000"). Auto Generate Save Location: Automatically create new file paths and folders based on updated prefixes. Set Save As Drawing: Enable saving associated drawings for selected files. Run Save As: Execute the macro to process all changes seamlessly. This macro saves hours of manual work, reduces errors, and ensures consistency in large-scale CAD projects. Perfect for engineers and CAD professionals looking to boost productivity! 📌 Source Code: [Link to code if shared, e.g., GitHub] 🔗 Subscribe for more automation tutorials! 💬 Comment below with questions or suggestions! #VBA #CAD #CATIA #Automation #FileManagement #Engineering

0 0 Expert
MIG (Metal Inert Gas) welding has become one of the most widely used welding processes in modern industry due to its high efficiency, automation capability, and compatibility with various materials. However, the type of arc transfer used in MIG welding plays a critical role in welding performance and quality. In this article, we explore the three main arc transfer modes in MIG welding: Short Arc, Spray Arc, and Globular Transfer — each with its own advantages and limitations. 🎯
