Abstract
The machine control system for a multi-spindle machine (10) includes a controller (42). The controller is operative to avoid machine down time by shutting down operation of the main drive motor (12) of the multi-spindle machine responsive to malfunctions as detected by a plurality of sensors. A controller is also readily programmable to modify the high and low shift points to optimize cycle times. The controller is further connectable to an administrative workstation (188) which includes a database (190) for producing a variety of analytical reports related to performance of the machine.
Claims20
A multiple spindle machine for machining a plurality of stock pieces wherein each stock piece is positioned within one of said spindles, wherein said stock pieces are simultaneously machined by components of said machine comprising:
- a timing shaft, wherein rotation of said timing shaft is operative to initiate and terminate machining of each of said stock pieces by said components;
- a main motor operatively driving both said timing shaft and said components, whereby said stock pieces are machined;
- an encoder in operative connection with the timing shaft wherein said encoder senses rotation thereof;
- and
- a controller in operative connection with said encoder and said main motor, wherein said controller shuts off said main motor when the speed of rotation of said timing shaft falls below a value.
