Abstract

A machine controller includes a memory and a processor configured for operating a machine control for automatically controlling apparatus for performing a machining process on a workpiece at least partially as a function of data relating to a parameter of the workpiece, and a gage control for automatically controlling gaging apparatus for collecting and processing the data relating to the parameter of the workpiece and storing the data in the memory. At least a portion of the memory in which the data relating to the parameter of the workpiece is stored, is configured as a shared memory so as to allow the machine control to immediately retrieve and use the stored data relating to the parameter of the workpiece. The controller has particular utility for use in controlling a honing process and a gaging process, which can be in-process or post-process, and which can be used for bore sizing and other parameters.

Claims

1. A machine controller, comprising:

a memory;

a processor;

a machine control for automatically controlling a honing machine operable for honing a bore of a workpiece at least partially as a function of data relating to a parameter of the workpiece, and a gage control for automatically controlling gaging apparatus for collecting and processing the data relating to the parameter of the workpiece and storing the data in the memory, the gage control being integrated with the machine control wherein the processor simultaneously runs a machine control program and a gaging program and is connected in operative control of the apparatus for performing the machining process and the gaging apparatus;

a control connection connecting the machine control and the gage control with the apparatus for performing the machining process and the gaging apparatus;

wherein at least a portion of the memory in which the data relating to the parameter of the workpiece is stored, is configured as a shared memory directly accessible by the machine control program and the gaging program separately of the control connection to allow the machine control program to immediately retrieve and use the stored data relating to the parameter of the workpiece in the machining process and to store data relating to the machining process in the shared memory for immediate retrieval and use by the gaging program; and

wherein the gage apparatus comprises an air gage column including a sensor interfaced with the controller for outputting data representative of a parameter of the bore of the workpiece thereto for use by the gage control, and the machine control automatically operates to move the sensor of the air gage column into the bore of the workpiece and store positional data relating thereto in the shared memory for immediate retrieval by the gaging program to correlate the sensor data with the positional data.

2. A machine controller as claimed in claim 1, wherein the machine control program uses the data relating to the parameter of the workpiece for adjusting honing parameters including feed, stroke speed, and dwell time.

3. A machine controller as claimed in claim 1, wherein the data relating to the parameter of the workpiece, comprises data relating to a size of the bore of the workpiece.

4. A machine controller as claimed in claim 1, wherein the data relating to the parameter of the workpiece, comprises data relating to a shape of the bore of the workpiece.

5. A honing machine controller, comprising:

a memory;

a processor;

a machine control for automatically controlling apparatus for performing a honing process on a workpiece at least partially as a function of data relating to a parameter of a bore of the workpiece, and a gage control for automatically controlling gaging apparatus for collecting and processing the data relating to the parameter of the bore and storing the data in the memory, the gage control being integrated with the machine control wherein the processor simultaneously runs a machine control program and a gaging program and is connected in operative control of the apparatus for performing the honing process and the gaging apparatus;

a control connection connecting the machine control and a gage control with the apparatus for performing the honing process and the gaging apparatus;

wherein at least a portion of the memory in which the data relating to the parameter of the bore is stored, is configured as a shared memory directly accessible by the machine control program and the gaging program separately of the control connection to allow the machine control program to immediately retrieve and use the stored data relating to the parameter of the bore in the honing process and to store data relating to the honing process in the shared memory for immediate retrieval and use by the gaging program; and

wherein the gage apparatus comprises an air gage column including a sensor interfaced with the controller for outputting data representative of a parameter of the bore of the workpiece thereto for use by the gage control, and the machine control automatically operates to move the sensor of the air gage column into the bore of the workpiece and store positional data relating thereto in the shared memory for immediate retrieval by the gaging program to correlate the sensor data with the positional data.

6. A honing machine controller as claimed in claim 5, wherein the machine control program uses the data relating to the parameter of the bore for adjusting honing parameters including feed, stroke speed, and dwell time.

7. A honing machine controller as claimed in claim 5, wherein the data relating to the parameter of the bore, comprises data relating to a size of the bore.

8. A honing machine controller as claimed in claim 5, wherein the data relating to the parameter of the bore, comprises data relating to a shape of the bore.

9. A honing machine controller as claimed in claim 5, wherein the honing process comprises honing the bore of a workpiece to a value determined as a function of data retrieved from the shared memory relating to a parameter of a previously honed bore, and processed and stored by the gage control program.
