Reduce time to CNC with NX CAM automation, part 2: CAM dialogs

This entry is part 2 of 2 in the series NX CAM automation

This entry is part 2 of 2 in the series NX CAM automationThis instruction shows how to redefine the NX CAM dialog boxes and save them as templates in order to record best manufacturing practices. The advantage of the method is simplicity, all customization work is done inside NX. Step-by-step instruction is given. 90% of automation in this video is done with this method: Why building NX CAM templates via dialogs? When creating a template, you reuse a set operations, each with its own individual parameters — tools, feeds and speeds, cutting parameters, etc. You make simplified selection for the actions that are unique for the new parts you manufacture with the template, this means that best practices can be reused and revised If best practices are recorded, less experienced users can be appointed to more complex tasks Area of use Detailed templates can be …

Reduce time to CNC with NX CAM automation, part 1: introduction

This entry is part 1 of 2 in the series NX CAM automation

This entry is part 1 of 2 in the series NX CAM automationIn NX, almost every aspect of CAM application can be customized. Customization can strongly improve the productivity of CAM application. Some tools are very simple, some require additional knowledge and skills. This is an introduction post, it gives an overview of the available tools. Please note that this post describes the automation tools that are likely to be covered in the blog later. In opinion of the author, the described tools can be used in most cases. There can be other automation methods not included here. Detailed information about each method will be added with the next posts. PRT templates These are based on a PRT template file, the one that is used for …

Manual impeller manufacturing in NX CAM, 4 axis mill-turn

This entry is part 4 of 4 in the series "Impeller manufacturing" NX CAM training 3-5 axis

This entry is part 4 of 4 in the series “Impeller manufacturing” NX CAM training 3-5 axisNX CAM multi-axis has a potential to save resources by making complex parts in 4 axis instead of 5 axis. This example shows the process for making a CNC toolpath for an impeller on a mill-turn machine (with simultaneous 4 axis). It will be useful for practicing skills in multi-axis milling and for CNC programmers who support mill-turn machines. Why replace 5 axis with 4 axis. Quite many geometries, which are made in 5axis can actually be made in 4 axis. In case it is a complex turn-mill part (like impeller) it can make sense to manufacture it in one single setup on a turn-mill machine. This can replace the (quite commonly used) process, when the …

Undercutting operations in NX CAM

This instruction shows how to create undercutting operations in NX. Two examples are shown: for planar and non-planar surfaces. Introduction. In NX CAM there is no dedicated undercutting operation. Most of the difficulties I faced in 3-axis undercutting were the following: When the direction of cutting levels is bottom – up When a non-planar surface is manufactured Both of this the situations can be solved with the use of Surface Area or Streamline methods. These methods allow defining a toolpath along the edges of the model in any direction. It means that you can follow complex surface and define direction to bottom-up. Additionally, you can model your own surfaces to guide the toolpath. Following examples show step-by-step instructions for both of the cases. Example 1. Undercutting with bottom-up …

Manual impeller manufacturing in NX CAM, 5 axis (semi)finish

This entry is part 3 of 4 in the series "Impeller manufacturing" NX CAM training 3-5 axis

This entry is part 3 of 4 in the series “Impeller manufacturing” NX CAM training 3-5 axisThis instruction shows the process for 5 axis operations, which can work as replacement for the automatic NX turbomachinery operations (as a part of impeller manufacturing series). This can work as a training material for 5 axis milling in NX CAM. Reasons for manual 5 axis. Generally, I use manual impeller manufacturing in 5 axis in some of the following cases: There is a small amount of material left after bigger tool and it is easier to remove it manually, than limiting NX Turbomachinery for certain area. In some cases, manual operation can be faster to create, than with NX turbomachinery. In case I want to use a non-ball end mill for …

Manual impeller manufacturing, 3 axis roughing in NX CAM

This entry is part 2 of 4 in the series "Impeller manufacturing" NX CAM training 3-5 axis

This entry is part 2 of 4 in the series “Impeller manufacturing” NX CAM training 3-5 axisThis instruction shows the process for creating roughing operations for an impeller (as a part of impeller manufacturing series). It can work as a training material for 3 axis manufacturing. Reasons for manual 3 axis. During my tests in impeller manufacturing, manual roughing operations have shown better performance compared to 5 axis. The difference in performance decreases, when areas to manufacture are difficult to reach from one position. In that case a combination of 3 axis and 5-axis (NX-turbomachinery) looks like an optimal choice. The main point in performing the 3 axis operations are axis position and cutting zone limitation. Step-by-step instruction. 3 axis operation from top. First of all, check …

Manual impeller manufacturing in NX CAM

This entry is part 1 of 4 in the series "Impeller manufacturing" NX CAM training 3-5 axis

This entry is part 1 of 4 in the series “Impeller manufacturing” NX CAM training 3-5 axisIntroduction. ‘Manual impeller manufacturing’ post series shows how to manufacture impellers in NX CAM. The instruction can also work as a training material for 3 and 5 axis manufacturing. This instructions should act as an addition to or replacement of the NX Turbomachinery toolset. Manual impeller manufacturing vs. NX turbomachinery. For manufacturing of impellers, NX Turbomachinery module is normally used. These operations allow making 5-axis movements with tool axis positioned between the impeller’s surfaces. The module contains roughing and finishing operations. Operations support InProcess workpiece and can be used alongside  with manual operations. In my opinion, NX turbomachinery operations have the following downsides: If you work in NX 8.5 or …
