Wire EDM Tooling - Praxis Precision Work Holding Subroutine G-Code~Solsylva CNC Plans Offsets G52 and Subroutine M98 and M99 There are a number of ways to use free or inexpensive 2D or 2.5D software to cut deeper or thicker stock than would be allowed with the single pass that is generated with the software. Mach3 has a Z offset function that lowers the Z axis on each successive pass. This function is straightforward and is described in the Mach3 manual. A simple way to lower the Z on each pass is to move the Z axis to a lower level by hand, and to then repeat the cut. The router's software does not know that the Z's height was changed, so the router cuts at a deeper level while thinking that it is at the original level. A similar method is to jog the Z axis lower and to re-zero the software to the new position before each new pass. Another way to lower the Z on each pass is the subroutine below. Note: With any of these methods it is important for the original clearance plane to be high enough to prevent the router from cutting into the stock as it is offset downward.
INDUSTRIAL NEWS /// WORLDWIDE INDUSTRY NEWS /// METAL & PLASTIC INDUSTRY GWizard: A CNC Machinist's Calculator for Feeds and Speeds We obsessed over G-Wizard It took years, we analyzed data from over 250 tooling catalogs, we built a powerful cutting physics engine with advanced algorithms that consider almost 60 different variables, and we worked with over 50,000 CNC'ers like yourself to make sure you'd have Better Tool Life, Surface Finish, and MRR with G-Wizard Master your Feeds and Speeds the easy way with G-Wizard. "I've been asking for this for 30 years from the CAM guys. How much do you spend on cutters in a year? G-Wizard pays for itself very quickly--you'll see in the 30-day Free Trial. "I'm in my 27th year and seen my share of 'machinist aid' software and this BY FAR packs the most punch for the dollar. "I'm a total Newbie on hobby mill and had the crazy idea to jump right in on some plasma cut hardened steel. "I am amazed at all the data that is available when using the G-Wizard.

1. Roughness : Terminology The quality of machined surface is characterized by the accuracy of its manufacture with respect to the dimensions specified by the designer. Every machining operation leaves characteristic evidence on the machined surface. This evidence in the form of finely spaced micro irregularities left by the cutting tool. Each type of cutting tool leaves its own individual pattern which therefore can be identified. 1. Roughness consists of surface irregularities which result from the various machining process. 2. It is the height of the irregularities with respect to a reference line. 3. The roughness width is the distance parallel to the nominal surface between successive peaks or ridges which constitute the predominate pattern of the roughness. 4. Roughness width cut off is the greatest spacing of respective surface irregularities to be included in the measurement of the average roughness height. 5. 6. 7. 8. 9. The rms value can be calculated as shown below. 1. 2. Ideal Roughness
PyCAM - Toolpath Generation for 3-Axis CNC machining Corner - The Front Page Introducing Designer 2.0 (and now 2.004) This major software rewrite has been recently released as an upgrade option. While maintaining the same familiar look and feel, ease of use and features of it's earlier versions, the underlying architecture of Designer 2 has been rewritten to allow future features that were not possible before. Included with the upgrade, which is available for $200, are many new features: Deep Carving is now available in version 2.004 (long bits required) Originally introduced in 2006 as the proprietary software for use with the CarveWright System, Project Designer software is as full featured and powerful as many much more expensive applications available. Rather than being forced to purchase all of the software at once, customers are able to add only those advanced features they need and grow their system as their skill levels and project requirements necessitate.
