What’s New in the Product Design & Manufacturing Collection

Many of you have likely already seen the What’s New in Inventor 2021 and Public Roadmap Update blog post in March and now we get to talk about what’s new in the Product Design and Manufacturing Collection.  As many of you know, PDMC is packed with powerful tools to aid in designing and manufacturing products. As part of the collection, there is a host of products to help with the overall design/manufacturing process like tolerance analysis, simulation, nesting, machining, and of course the collection wouldn’t be complete without AutoCAD and its industry-specific toolsets.

Let us take a look at some of the key enhancements in the Product Design and Manufacturing Collection.

Inventor Nastran

Inventor Nastran provides finite element analysis (FEA) tools for engineers and analysts. Simulation covers multiple analysis types, such as linear and nonlinear stress, dynamics, and heat transfer.

Inventor Tolerance Analysis

Inventor Tolerance Analysis allows you to do a 1D tolerance analysis directly on your 3D model. It helps you better understand the impact of mechanical fit and performance based on the cumulative dimensional variation and lets you try various scenarios to find the best fit to reduce machining cost while maintaining proper fit/function.

In this release, we worked on assembly stability issues that contained

We have also blocked renaming components in the Tolerance Analysis environment to prevent a mismatch with the Inventor browser names. Rename faces and edges are allowed.

Inventor CAM

Inventor CAM integrates 2.5-axis to 5-axis milling, turning, and mill-turn capabilities right inside of Inventor. The primary updates to Inventor CAM was around Turning and overall stability/robustness enhancements.

In computer (new behavior): This option allows the user to output a canned cycle profile already compensated for the tool nose radius. The benefit of this approach is, the user does not need to enter the tool nose radius compensation at the control.

A new parameter “Retraction Policy” was added to the Linking tab of Turning Profile Roughing operations. This parameter is only available for Inside Profiling mode when the cycle is set to Horizontal Passes and the machining direction is set from Front to Back. This parameter is not available when the Use Canned Cycles parameter is checked on.

When Retraction Policy is set to Minimum Retraction, the tool retracts minimally in Z after every cutting pass up to the Z Clearance value (existing behavior). When this parameter is set to Full Retraction, the tool retracts to Safe Z after every cutting pass (new behavior).

In previous versions, the profile roughing strategy often created shallow cutting passes that resulted in the production of thin chips. The parameter “Even depths of cut” was added to fix this issue. This parameter, when checked on, ensures that every cutting pass creates a chip of even thickness within every machining region inside the machining limits.

User Benefit: If the depth of the cut is shallow, it produces a thinner chip that could curl around an insert and damage the surface finish of the part. Thinner chips also prevent the dissipation of heat from the tool insert, thereby reducing the life of the tool. Generating a toolpath with even depths of cut optimizes the machining process by creating chips of an even thickness which improves the surface finish of the part and increases tool life.

The parting strategy previously supported a reduced feed rate at a user-specified radius away from the center by turning on the “Use reduced feed” option. Now users can also specify a reduced spindle speed when this option is turned on. Programming a reduced spindle speed just before the part is cut off allows the part to be safely separated from the stock without damaging it.

Factory Design Utilities 

Inventor Factory lets you plan and validate factory layouts for the most efficient equipment placement to maximize production performance.

AutoCAD

Outside of Inventor and the Inventor products in the collection, AutoCAD is one of the most widely used tools in the Product Design and Manufacturing Collection. With more people working remotely and with the ability to use AutoCAD on virtually any device (desktop, web, mobile)  its much easier to get your job done. AutoCAD can also use any cloud (Dropbox, box, OneDrive or Google Drive) to make it even easier to work remotely.

There are some great enhancements in AutoCAD 2001, here are a few of them.
