Description: |
| Abstract
A machine tool, such as a milling machine, embodying a control system employing fluid amplifiers for controlling and actuating in selected sequence a plurality of steps in an automatic cycle of the machine. Means are provided whereby the selective programming of the cycle may be set up at a central control console conveniently located for the operator, and sequentially executed by operation of relatively high fluid pressure in response to relatively low pressure fluidic signals. The low pressure fluidic signals, as on the order of about 1 psi or less, are selectively employed to control flow of relatively high pressure fluid to cause the relatively high pressure fluid to actuate power means such as hydraulic cylinders for causing programmed relative movements of work holding and tool holding means of the machine.
