Abstract

Systems and methods for configuring a power tool. One system includes a power tool communication system that includes an external device and a power tool. The external device includes a user interface configured to receive a first selection to enable a feature of a power tool, and receive a second selection of a threshold of a motor characteristic of the power tool. The power tool includes a motor within a housing. The power tool receives the selected feature and the selected threshold from the external device. The power tool includes a sensor configured to monitor the motor characteristic of the motor. The power tool further includes an electronic processor that controls the motor to operate according to the selected feature and adjusts an operating parameter of the motor when the motor characteristic is determined to cross the selected threshold.

First claim

We claim:

1. A power tool communication system comprising:
an external device including
a user interface configured to
receive a first selection of a type of material to be cut,
receive a second selection of a thickness of a material to be cut,
receive a third selection of a blade type of a blade to be used to cut the material; and

a first electronic processor configured to control the user interface to display a recommended motor speed based on at least one selected from the group of the first selection of the selected blade type, the second selection of the selected type of material, and the third selection of the selected thickness of the material;

a power tool including
a housing,
a motor within the housing, wherein the motor includes a rotor and a stator,
a transmission coupled between the motor and a reciprocating spindle,

wherein the transmission converts rotational motion of the motor to reciprocating motion of the reciprocating spindle,
a blade holder coupled to the reciprocating spindle,
a wireless communication controller configured to receive the recommended motor speed from the external device, and
a second electronic processor coupled to the wireless communication controller, wherein the second electronic processor is configured to control the motor to operate at the recommended motor speed;

wherein the first electronic processor is configured to display a recommended blade type based on at least one of the group consisting of the selected type of material to be cut and the selected thickness of the material to be cut;
wherein the user interface is configured to receive the third selection of the blade type after the display of the recommended blade type; and
wherein the first electronic processor is configured to determine the recommended motor speed after receiving the third selection of the blade type and based on the third selection of the blade type.

2. The power tool communication system of claim 1 , wherein the first electronic processor is configured to recommend an increasing number of teeth per unit of length of the recommended blade type as the selected thickness of the material decreases.

3. The power tool communication system of claim 1 , wherein the first electronic processor is configured to determine the recommended blade type such that a predetermined number of teeth of the blade engage the material to be cut during a cutting operation.

4. The power tool communication system of claim 1 , wherein the first electronic processor is configured to increase the recommended motor speed as a softness of the selected type of material increases.

5. The power tool communication system of claim 1 , wherein the first electronic processor is configured to decrease the recommended motor speed as a number of teeth per unit of length of the selected blade type increases.

6. The power tool communication system of claim 1 , wherein
the first electronic processor of the external device is configured to determine a ramp up period for the motor to reach the recommended motor speed based on the selected thickness of the material, wherein the ramp up period decreases as the selected thickness of the material decreases;
the wireless communication controller of the power tool is configured to receive the ramp up period from the external device; and
the second electronic processor of the power tool is configured to control the motor to reach the recommended motor speed in accordance with the ramp up period.

7. The power tool communication system of claim 1 , wherein
the user interface of the external device is configured to receive a user input to adjust the recommended motor speed to an adjusted motor speed;
the wireless communication controller is configured to receive the adjusted motor speed from the external device; and
the second electronic processor is configured to control the motor to operate at the adjusted motor speed.

8. A method of controlling operation of a power tool, the method comprising:
receiving, via a user interface of an external device, a first selection of a type of material to be cut;
receiving, via the user interface of the external device, a second selection of a thickness of a material to be cut;
receiving, via the user interface of the external device, a third selection of a blade type of a blade to be used to cut the material;
determining, with a first electronic processor of the external device, a recommended motor speed based on at least one selected from the group of the first selection of the selected blade type, the second selection of the selected type of material, and the third selection of the selected thickness of the material;
displaying, on the user interface of the external device, the recommended motor speed;
receiving, with a wireless communication controller of the power tool, the recommended motor speed from the external device, the power tool including
a housing,
a motor within the housing, wherein the motor includes a rotor and a stator,
a transmission coupled between the motor and a reciprocating spindle,

wherein the transmission converts rotational motion of the motor to reciprocating motion of the reciprocating spindle, and
a blade holder coupled to the reciprocating spindle;

controlling, with a second electronic processor of the power tool, the motor to operate at the recommended motor speed, the second electronic processor being coupled to the wireless communication controller;
determining, with the first electronic processor of the external device, a recommended blade type based on at least one of the group consisting of the selected type of material to be cut and the selected thickness of the material to be cut; and
displaying, on the user interface of the external device, the recommended blade type;
wherein receiving the third selection of the blade type includes receiving, via the user interface of the external device, the third selection of the blade type after displaying of the recommended blade type; and
wherein determining the recommended motor speed includes determining, with the first electronic processor of the external device, the recommended motor speed after receiving the third selection of the blade type and based on the third selection of the blade type.

9. The method of claim 8 , wherein determining the recommended blade type includes determining, with the first electronic processor of the external device, that the recommended blade type includes an increasing number of teeth per unit of length as the selected thickness of the material decreases.

10. The method of claim 8 , wherein determining the recommended blade type includes determining, with the first electronic processor of the external device, the recommended blade type such that a predetermined number of teeth of the blade engage the material to be cut during a cutting operation.

11. The method of claim 8 , wherein determining the recommended motor speed includes increasing, with the first electronic processor of the external device, the recommended motor speed as a softness of the selected type of material increases.

12. The method of claim 8 , wherein determining the recommended motor speed includes decreasing, with the first electronic processor of the external device, the recommended motor speed as a number of teeth per unit of length of the selected blade type increases.

13. The method of claim 8 , further comprising:
determining, with the first electronic processor of the external device a ramp up period for the motor to reach the recommended motor speed based on the selected thickness of the material, wherein the ramp up period decreases as the selected thickness
