Waterjet 5 assi per materiale lapideo

Introduction

Jekran manufactures machines for cutting stone and composite slabs, using a special pump system of its own design. The machine's large size requires high rapid speeds, the beam movement with two synchronized motors, and the need to reduce axis homing times.

The use of high-pressure water jet poses several problems of taper compensation and beam deviation.

The machining operations are defined by a CAM specialized in complex machining and capable of making the most of water cutting technology.

Solution

ISAC offered the Costantino CNC with a ready-to-work application, and a package of brushless motors and digital drives connected with EtherCAT fieldbus, and multi-turn absolute encoders to eliminate dead times due to axis homing.

Exploited capacities

Torch height control
Tool radius compensation
Running the program in reverse
Modulation of trajectory speed with respect to distance from the edge
TCP to interpret the tool tip trajectory even in case of compensated bi-rotary head.
TCP parameters autotuning
High-speed interpolation
Customer-customized IEC61131 PLC logic

Results

The integration between CNC and drives significantly reduces machine setup times, reduces downtime during use, and enables a significantly higher level of remote customer support than alternative solutions.

The interpolation quality and TCP features contribute to optimizing the quality of the resulting cut.
