Interface of Tpa IsoCNC, Tpa numerical control that manages automations based on ISO programming

General features

IsoCNC is a numerical control with all the necessary features and performance to manage automations based on an ISO programming. The interface of this product was studied in its every part, so that it could be used with a touch-screen video, even without keyboard and mouse. With this in mind, its graphical style shows some detailed parts (e.g., the tool and machine parameter section), combined with a clear and simple context.

Functional features

This numerical control’s potentials are striking:

  • ISO lists run step-by-step;

  • insertion of parts of the list (while the machine is paused) after the ISO instruction on which we stopped and restarting from the following instruction;

  • starts running from any point of the list;

  • any MDI instruction can be inserted at any time when running (or not running);

  • tool correction either on a plane (2D) or in a space (3D);

  • 3 or 5-interpolated-axis ISO lists;

  • explicit definition of the kinematics of the interpolating axes (especially in the case of a 5-axis heads that does not use the canonical rotating axes).

We can find in one interface all the parts necessary to interact with the machine: dedicated dashboards, full communication with I/Os and misc devices, viewing and editing (also guided) of ISO lists, graphical view of the path, tool parameters (with graphical help), recalling of programs different from the configurable product (e.g., a program CAD or the simple Windows Calculator). The length of ISO programs is virtually limitless, as the ISO gets processed bit by bit and constantly sent to the numerical control.

Some of the operational sections of IsoCNC are protected by password levels, so that it is possible to separate operations that can be accessed by machine (or NC) maintenance, those that can be accessed by plant or department managers, and those that can be run by machine operators. Tool parameters are customizable, and those fields too can be protected by password levels, either for reading and writing.

IsoCNC is a product that can interface the machine 3D simulator for a full feasibility analysis of programs, both to avoid potential machine collisions and to evaluate the running hours.


This system has an interpolation lookahead, managing up to 4096 blocks per interpolation channel. The maximum interpolation speeds depend on the length of ISO blocks and on the CPU of the numerical control selected for the application (e.g., with a CN2008 SE we can get a 25 m/min speed with 1 mm blocks). As previously mentioned, the program length is only limited by the supervisory PC used to manage the text files, while its computing and execution can virtually be endless.
