Tool path optimization
CAM software helps users optimize toolpaths.
The Rainbow Shading method displays the processing order and the axis is displayed in reverse color. Visual inspection of tool geometry, speed and feed can be considered. Since the new CAM features describe the tip characteristics, the user can see the actual tooling and effects, accurately display the feed rate and effect, and the surface quality of the workpiece, allowing surface finish values ​​to be predicted before actual machining.
The redistribution of points provides a way to reduce processing time. In one example, a five-axis machining center with a spindle speed of 7500 mm/min can speed up the cycle time by 39% by comparing point redistribution with standard tolerance data. The redistribution of points allows the programmer to easily handle the smoothness of the tool path and the assignment of points on the path to achieve these results.
User value
Either way, for mold manufacturing companies, the advantages of using five-axis machining technology are mainly reflected in the following aspects:
1. Shorter processing time: Five-axis machining can reduce the manufacturing process and the number of workpiece clamping and EDM area and mold polishing, thus greatly shortening the overall processing time and shortening the delivery cycle.
2, improve the quality: the use of shorter tools can reduce the deviation, to obtain higher processing accuracy and more stable surface quality.
3, reduce costs: five-axis machining can extend the life of the tool, but also reduce the use of other processing equipment, such as reducing electrical processing equipment can reduce the use of electrical levels.
In the actual application process, experienced users will also set a lot of templates, which can save time and reduce the error rate of future programs, and can carry out complete process simulation on the computer to prevent errors in the workshop processing.
The user may need to adjust the clamping strategy when using five-axis machining in order to take into account the workpiece characteristics as much as possible in the programming of the five-axis machining. Standard clamping devices generally do not allow access to multiple sides of the workpiece, while the dedicated five-axis tooling mechanism and magnetic clamping mechanism provide easy access to the part being machined and are therefore favored by the user.
The advantages of five-axis machining include a variety of machining methods (three-axis HSM, positioning five-axis, continuous five-axis, five-axis drilling, etc.), which requires only one piece of equipment, and that the spindle speed and feed rate are faster. Five-axis machine tools also have a tendency to reduce in size and have better stiffness, which can further improve the efficiency of enterprise applications.
The technology behind five-axis machining and high-speed machining continues to improve and is being used more widely. Advances in these technologies and equipment, although at a glance the investment is relatively high, the benefits in terms of tool life, efficiency and actual operating costs have completely offset these initial costs.
