연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The invention claimed is: 1. A method for reducing vibrations during resurfacing of a vehicle brake component with a brake lathe having a variable speed spindle motor, an output spindle rotationally driven by the variable speed motor adapted to couple the brake lathe to a vehicle brake component, and at least one adjustable cutting tip adapted to engage a surface of the vehicle brake component, comprising the steps of: detecting vibrations resulting from contact between the at least one adjustable cutting tip with a vehicle brake component surface; altering a drive speed of the variable speed spindle motor responsive to a level of said detected vibrations exceeding a predetermined threshold. 2. The method of claim 1 wherein altering a drive speed of the variable speed spindle motor alters a linear feed rate associated with the at least one adjustable cutting tip. 3. The method of claim 1 wherein altering a drive speed of the variable speed spindle motor alters a rotational speed of the output spindle. 4. The method of claim 1 wherein further including the step of altering a placement position of at least one cutting tip responsive to a level of said detected vibrations exceeding a predetermined threshold to alter a depth of cut on a brake component surface. 5. A method for reducing the development of vibrations during resurfacing of a vehicle brake component with a brake lathe having a variable speed spindle motor, an output spindle rotationally driven by the variable speed motor adapted to couple the brake lathe to a vehicle brake component, and at least one adjustable cutting tip adapted to engage a surface of the vehicle brake component, comprising the step of: altering a drive speed of the variable speed spindle motor to a rotational speed of the output spindle during engagement of the at least one cutting tip with the surface of the vehicle brake component. 6. The method of claim 5 wherein said step of altering said drive speed of the variable speed spindle motor includes continuously varying said drive speed within a predetermined speed range to continuously vary said rotational speed of the output spindle. 7. The method of claim 5 wherein said step of altering said drive speed of the variable speed spindle motor includes varying said drive speed in a stepwise manner within a predetermined speed range at discrete intervals. 8. The method of claim 5 wherein further including the step of altering a drive speed of the variable speed spindle motor to alter a linear feed rate associated with the at least one adjustable cutting tip. 9. A method for attenuating vibrations during resurfacing of a vehicle brake component with a brake lathe having a controller, a rotationally driven output spindle adapted to couple the brake lathe to a vehicle brake component, and at least one adjustable cutting tip adapted to engage a surface of the vehicle brake component, comprising the step of: utilizing the controller to automatically alter a rotational speed of the output spindle during cutting engagement of the at least one cutting tip with the surface of the vehicle brake component. 10. The method of claim 9 wherein the controller is programmable, and further including the step of programming the controller to automatically vary said rotational speed of the output spindle during cutting engagement of the at least one cutting tip with the surface of the vehicle brake component. 11. The method of claim 9 further including the step of utilizing the controller to automatically alter a linear feed rate associated with the at least one adjustable cutting tip. 12. A method for attenuating vibrations during resurfacing of a vehicle brake component with a brake lathe having a programmable controller, a rotationally driven output spindle adapted to couple the brake lathe to a vehicle brake component, and at least one adjustable cutting tip adapted to engage a surface of the vehicle brake component, comprising the steps of: programming the controller to regulate a rotational speed of the output spindle; and, utilizing the controller to vary a rotational speed of the output spindle in response to said programming, during cutting engagement of the at least one cutting tip with the surface of the vehicle brake component. 13. The method of claim 12 wherein the step of utilizing the controller to vary a rotational speed of the output spindle further includes controlling a variable speed spindle motor operatively coupled to drive the output spindle at said rotational speed. 14. The method of claim 11 further including the steps of programming the controller to regulate a linear feed rate of the at least one adjustable cutting tip, and utilizing the controller to automatically alter a linear feed rate associated with the at least one adjustable cutting tip. 15. A brake lathe for resurfacing of a vehicle brake component, comprising: a variable speed spindle motor carried by a support structure and controlled by a motor controller; an output spindle carried by the support structure and rotationally driven by the variable speed motor, said output spindle adapted to couple the brake lathe to the vehicle brake component during a resurfacing procedure; at least one adjustable cutting tip carried by the support structure and adapted to engage a surface of the vehicle brake component during the resurfacing procedure; and a microprocessor operatively coupled to the motor controller, said microprocessor configured to direct the motor controller to alter a drive speed of the variable speed spindle motor to attenuate vibrations occurring during the resurfacing procedure. 16. The brake lathe of claim 15 wherein altering the drive speed of the variable speed spindle motor alters a linear feed rate associated with the at least one adjustable cutting tip. 17. The brake lathe of claim 15 wherein altering the drive speed of the variable speed spindle motor alters a rotational speed of the output spindle. 18. The brake lathe of claim 17 wherein the microprocessor is further configured to direct the motor controller to continuously vary the drive speed of the variable speed spindle motor within a predetermined speed range to continuously vary the rotational speed of the output spindle. 19. The brake lathe of claim 17 wherein the microprocessor is further configured to direct the motor controller to vary the drive speed of the variable speed spindle motor in a stepwise manner within a predetermined speed range over discrete intervals to continuously vary the rotational speed of the output spindle. 20. The brake lathe of claim 15 wherein said microprocessor is further configured to control adjustments to a placement position of the at least one cutting tip to alter a depth of cut by the cutting tip on the vehicle brake component surface responsive to a level of said detected vibrations exceeding a predetermined threshold.
