The Fanuc control macro performs roughing and finishing of large diameter thread, internal or external. It uses roughing and finishing strategies that allow threads to be produced with very high pitches, while maintaining low cutting forces and good surface finishes. In the case of both the screw and the leadscrew, roughing and finishing can be carried out with standard radius-shaped tools, such as a radius-shaped groove tool or tools with R-shaped inserts, or better still, when angles permit, standard V-shaped (e.g. VNMG) or D-shaped (e.g. DNMG) turning tools. It is also possible to use tools with a flat line such as grooving tools.
The Fanuc control macro performs roughing and finishing of large diameter thread, internal or external. It uses roughing and finishing strategies that allow very high pitch threads to be produced with low cutting forces and good surface finishes. Macro suitable for large diameter thread where shaped tools cannot be used. In large threads and consequently with high pitches, the use of shaped tools can present major problems of vibration and tool breakage.
In the case of both the screw and the leadscrew, roughing and finishing can be carried out with standard tools of radius shape; groove tools of radius shape or with inserts of form R or better still, when angles permit, standard turning tools of form V (e.g. VNMG) or D (e.g. DNMG). It is also possible to use tools with a flat line such as grooving tools.
The macro allows you to freely set the inclination degrees of the two sides of the thread. It also allows you to set the corner radii on both external and internal edges. For example, it can be used to machine buttress with standard and non-standard angles, trapezoidal and metric threads.
By setting the angle of the two flanks to zero, it is possible to perform spidering on bushings or square threads.
In roughing, the macro will perform for each X step a series of cuts to open the thread groove, committing the tool radius equal to a maximum value set with a parameter. In finishing, the macro allows you to set the value of the maximum ridge along the profile so as to control the roughness on the whole profile, both on the sides and on the bottom and also on the radii.
For trapezoidal thread where the radii at the bottom are almost zero, it is possible to set flat, parting or special tools.
The threading macro makes it easy and reliable to machine large diameter threads, helping to manage dimensions and reducing effort. In addition, using standard tools significantly reduces production costs, as no special shaped tools are required, which in addition to high costs create enormous cutting efforts.
The macro can be executed on all lathes with Fanuc control from series zero to series 31. For details, please refer to the manual with particular attention to the paragraph “Warnings”.
How do I know what exactly the macro does?
Click on the ‘MANUAL’ icon to find the macro documentation with examples and parameter descriptions. Pay particular attention to the last paragraph ‘Warnings’.
After how long do I receive the macro?
After clicking on the buy button you will be directed to the purchase page. If you pay by credit card or PAYPAL, at the end of the process you will find in your personal area the macro ready for downloading with its manual and parameter diagram. If you pay by bank transfer, the macro will only be available once the amount has been credited.
How do I load the macro into the machine?
The macros for sale online do not require our presence for installation. Once purchased, the macro will be loaded onto your CNC machine just like a normal programme. To transfer the programme to the machine tool, use the method already in use on your machine (SERIAL, USB, PCMCI, NETWORK).
On how many machines in my workshop can I use the macro?
With the purchase of the machine you also acquire the licence to use the macro for all the machines in your workshop. It is not possible to sell or transfer the macro to third parties. For more information, please read the contractual conditions carefully.
Why are some macros not saleable online?
Some macros are marked ‘NOT SELLABLE ONLINE’ because they require the presence of a technician for installation. This is the case, for example, when customised screens for entering parameters have to be installed.
