•Design
The following information is intended to assist with determining the weight of a gantry on a table that is accelerated by the
EDGE Pro Ti motors (031143).
A theoretical table configuration using a single-side drive with rack and pinion mechanics is the basis for the calculations.
The pinion gear diameter is 50 mm (1.9 in.). Table 4 provides the suggested values for the weight of the gantry and
multiple gearbox ratios based on this hypothetical table.
Different table designs have different weight values. These values have been calculated with the torque equation, which
compares the maximum continuous torque of the motor to the theoretically calculated inertia of the cutting machine.
In the following table, the figure for maximum linear speed is based on the pinion diameter and gearbox ratio for a single
side drive using a 50 mm (1.9 in.) pinion gear. This figure does not include the limitations of table mechanics which can
significantly reduce this value. To determine the gantry weight for a dual gantry setup, increase the weight of the
single-side drive by 40%.
Table 4 Gantry sizing
Properly sizing the machine to performance specifications requires mechanical engineering and motion engineering
expertise. Table manufacturers are responsible for the optimal sizing and performance characteristics of the complete
machine. The EDGE Pro Ti can be used in many different configurations but the final performance characteristics of the
machine depend on the total solution provided by the table manufacturer.
Placement of system components
• Place all system components in position prior to making electrical, gas and interface connections. See
Mounting the CNC on page 39 for details.
• Ground all system components to earth. See Recommended grounding and shielding on page 43 for
grounding details.
