Inches To Metric Conversion in Mastercam

By |2018-09-17T08:38:20+00:00September 17th, 2018|Categories: Mastercam, Tech Tips|0 Comments

There is a new easy way to scale Mastercam solids, surface, and wireframe models from Metric to Inches and vice versa. This article will explain how to do it. Let’s start out with a basic Parasolid file in inch units (shown above). After using Analyze Distance, we can see the part size is 19.7. Now, we can go to the Transform tab, select the Scale function and select our model. There are two settings that help make the conversion. First, we should make sure that our style of scaling is set to Uniform. This applies the scaling uniformly across the part instead of different values for different axis. Next, under the Uniform section, there are three icons across the bottom of our scale. The first one is for Metric Conversion, the second is for Scaling to Inch Units, and the last one opens up the Scale Calculator. These options are only in the Uniform style of scaling. In older versions, we would have to type 25.4 into the scaling to convert the size to metric for us. Now, all we have to do is select the Metric Scale option and now this part automatically converts from 1.97 inches to the [...]

Mastercam 2019 Section Views

By |2018-09-10T08:32:11+00:00September 10th, 2018|Categories: Mastercam, Tech Tips|0 Comments

There’s a new function in Mastercam 2019 which will help you visualize part features with more clarity. Section View can be activated relative to any saved planes and you can choose multiple styles of display. You will notice some new icons in the Planes Manager and on the View Ribbon tab. If you click the drop-down arrow to the right of either icon you can see that section viewing can be applied to stock models, shaded entities, whether they be surface, solid or polygon mesh entities, wireframe geometry, and toolpath displays. Each of these can be activated or deactivated independently. The final option to Show Caps heals the section through. Next, to enable Section Viewing, simply check the box in the appropriate row for the plane that you want to use. When you click the Section View button the display updates instantly. Toggling the Show Caps option also instantly updates the view. Since View Sheets can capture all these settings it’s very easy to save and quickly recall highly customized snapshot of your working environment, showing sections through part geometry, toolpath, and stock models independently. You can even activate multiple planes to generate compound sections. As you can see, this [...]

CMM Master – Portable Inspection System

By |2018-08-31T08:33:48+00:00August 31st, 2018|Categories: 3D Scanning, Tech Tips|0 Comments

Today we are going to talk about a portable CMM called the CMM Master. The CMM Master is based on the Renishaw Equator, and powered by Verisurf’s AUTOMATE software. The working volume is approximately 12” X 12” X 6” up from the plate. It has been volumetrically error mapped with the Verisurf software to an accuracy of +/- .0005î, making it more accurate than the standard Equator. Its single point repeatability is within a couple of tenths! Verisurf's AUTOMATE software, allows you to create complete automated inspection plans. Once this plan is created, you click on the Play button and AUTOMATE takes over. It runs the full inspection plan, collects data for each feature, and at the end of the routine automatically generates a date and time stamped report. The CMM Master is very fast. It has a maximum movement speed of 500 mm/s, or 19.7î in/sec. If you choose to use the probe as a scanner, you input the scan parameters in Verisurf, and the probe scans at a maximum speed of 100 mm/s, almost 4î per sec. At the same time, it can collect up to 1000 points/sec. The CMM Master has built in, user-friendly Calibration Routines that [...]

Mastercam 2019 Model Prep Alignment

By |2018-08-27T08:18:25+00:00August 27th, 2018|Categories: Mastercam, Tech Tips|0 Comments

In Mastercam 2019, three functions have been added to the Model Prep tab: Align to Plane, Align to Face, and Align to Z. Align to Plane lets you quickly prepare a solid body for machining by positioning it in line with a specific plane. You can move the solid and additional selected geometry to align with an existing plane. You can also create a new work coordinate system (WCS) based on a selected face of the solid. This is helpful when you must align a solid to an entity that must remain in a particular orientation. The Mastercam function, Solid Position, has been renamed Align to Face and has been enhanced to make it easier to use. You can still easily mate the selected faces of two solids, but with the improved Align to Face, you can also align the edges of the solids that you mate. Choose any linear edge on the solid to be moved and it aligns to the X-axis of the gnomon. Then, after placing the solid on the target body, pick a linear edge to rotate the moved solid perpendicular or parallel to it. Align Solid Body, which was previously on the Turning tab, has [...]

3D Printing Accuracy, Precision, and Tolerance

By |2018-08-16T08:49:09+00:00August 17th, 2018|Categories: 3D Printing / Additive Mfg, Tech Tips|0 Comments

This post will cover some of the fundamental concepts in 3D printing: accuracy, precision, and tolerance. Understanding these key concepts and the differences between them is necessary for achieving the level of performance you desire when evaluating any 3D printing technology. First and foremost, you need to understand that just because a printer lists a high-resolution in a spec-sheet, it does not mean that your parts will be accurate or precise. This is a common misconception and will be covered in a future blog post. Let’s begin by defining the three terms (accuracy, precision, and tolerance) and then we will use common examples to help you understand each. Accuracy is how close a measurement is to true-value. A common example is a target where the true-value is the bullseye. The closer you are to the bullseye, the more accurate you are. In 3D printing, the true-value equals the dimensions of your CAD model and how close the 3D print lines up with those dimensions. Precision measures the repeatability or consistency. For example, your shots on a target could be hitting near the same spot every time but not necessarily on the bullseye. In 3D printing, this translates into reliability, i.e. [...]

Mastercam 2019 Solid Hole Function

By |2018-08-13T08:17:53+00:00August 13th, 2018|Categories: Mastercam, Tech Tips|0 Comments

A new function called Hole is now available on the Solids tab in Mastercam 2019. This function automates the punching of cylindrical holes in primitive solids, saving you from creating circles and extruding them. Set the hole dimensions and the hole type. You can create a simple cylinder or select from the following hole types: Counterbore Countersink Counterdrill Taper Click in the graphics window to place it on the solid. Press Enter to view the new hole. The hole remains live and you can place copies of it on the part or modify any of its parameters until you exit. Create and save commonly used holes in a preset library. You can use these presets in future sessions of Mastercam. Mastercam converts hole dimensions stored in a preset library to the current units (inch to metric, or metric to inch). The Solids Manager displays this function's operations.

Onshape Branching and Versioning

By |2018-08-10T08:33:07+00:00August 10th, 2018|Categories: 3D Printing / Additive Mfg, Tech Tips|0 Comments

One of the challenges in product design is in keeping the brainstorm workspace organized. You will probably explore many “what if” scenarios to come up with a good starting point for the product and Onshape has a great design and collaboration solution for this called Branching and Versioning. In this example, we are looking for a creative guitar face for the guitar we are designing. In order to leverage our colleagues' creativity, we first need to Create a version. This captures a snapshot of your design in time. Having that, you can then leverage the Branch functionality and branch off to a workspace to experiment in without affecting the original design. We've created several branches springing from the Base Version. Each of our colleagues now have their own workspace to brainstorm in independently. Once everyone has had a chance to experiment in their own workspace, you can quickly cycle through what everyone came up with. Onshape also lets you compare Versions, Workspaces, or even moments in History in a Part Studio. If there is one particular design that you would like to implement, you can choose to Merge it back to the base version and continue designing from there. As [...]
